5 1GENERAL 1 SUMMARY These specifications describe Hipulse Uninterruptible Power System (UPS) as a stand-alone unit or connected in parallel with or without the need for a centralized Main Static Switch (MSS). Hipulse automatically maintain AC power within specified tolerances to your critical load, without interruption, during failure or deterioration of the mains, by way of adequate battery back-up. Hipulse can be expandable by paralleling additional modules of the same rating, to provide for module redundancy or capacity growth requirement. Hipulse is carefully designed to maximize the "availability" of your critical loads to ensure that your business is protected to the extent possible against power failure and/or power quality problems. This is the prime objective for which the Hipulse is built. Besides this, Hipulse is designed to address many other "customer values". Fig kVA Hipulse STANDARDS Hipulse is designed and manufactured in accordance with the following applicable standards EN EN ENV UPS - General and safety requirements for UPS UPS - EMC Requirements UPS - Performance requirements and test methods Hipulse is CE marked in accordance with EEC directives 73/23 low voltage and 89/336 electromagnetic compatibility. The Quality System for the engineering and manufacturing facility is certified to conform to Quality System Standard ISO

6 1 SYSTEM PROTECTION Hipulse has built-in protection against the following power events: surges, sags and over-current from the AC source, over voltage and voltage surges. These problems can be originated from output terminals of paralleled sources and load switching and circuit breaker operation in the distribution system. Hipulse is also protected against: sudden changes in output load short circuits at the output terminals permanent damage to itself and the connected load for all predictable types of failures cascading failure of solid-state devices by using fast-acting current limiting devices Internal Hipulse malfunctions cause the module to trip off-line with minimum damage to the module and provide maximum information to maintenance personnel regarding the reason for tripping off line. Customer Values The expensive, sophisticated and sensitive load equipment of customer's critical applications are thoroughly protected by Hipulse against all kinds of predictable power supply abnormalities. Hipulse will provide several solutions for matching any requirements. 6

7 2SYSTEM DESCRIPTION 2 MODES OF OPERATION Hipulse operates as a true on-line system in the following modes: Normal Mains Bypass Mains Q1 Q2 Q3 RECTIFIER DC BUS BATTERY CIRCUIT BREAKER INVERTER BATTERY STATIC SWITCH Q4 Hipulse Single Module System (SMS) Crit ical Load Diagram 1 UPS Module Operation (Single Module System-SMS) A. Normal: Your critical AC load is continuously powered by the Hipulse inverter. The rectifier/charger derives power from the mains converting this to DC power supply the inverter, while simultaneously float charging the battery system. Power supplied by the Hipulse inverter is, to within close tolerances, at rated voltage and frequency. B. Emergency: Upon failure of the mains, your critical AC load is powered by the inverter which, without any switching, obtain power from the battery system. There will be no interruption in power to your critical load upon failure or restoration of the mains. C. Recharge: Upon restoration of the mains, power to the rectifier/charger initially is restricted by a gradual power walk-in by design. Following this relatively short power walk-in period, the rectifier/charger powers inverter and simultaneously recharge the battery. This will be an automatic function and will cause no interruption to your critical load. D. Maintenance Bypass: Hipulse is taken out of service for maintenance or repair. It is possible to transfer the critical load from Inverter to Maintenance Bypass Line by means of Maintenance Bypass Isolator. The transfer process will cause no interruption to your critical load. 7

8 2 E. Off-Battery: If the battery system only is taken out of service for maintenance, it is disconnected from the rectifier/charger and inverter by means of (an) external disconnect breaker(s). Hipulse will continue to function and meet all of the specified steady-state performance criteria, except for the power outage back-up time capability. Customer Values A. Under normal power conditions, the UPS is an unbeatable source of clean, regulated power to your load. Optionally, by disabling the bypass supply, the UPS can be used as a frequency converter from 50 to 60 Hz and vice-versa. B. In the "emergency" conditions, the customer gets the value of uninterruptible regulated power supply for a duration of battery autonomy time. This ensures the critical applications to have the most desired regulated power even in mainsfailure condition. C. A fully charged battery is the best insurance that your application will be safe in the event of a mains power failure. During normal operation bypass thus ensures that the battery is recharging to full ready condition. D. Critical interventions can be carried out without affecting the power supply to your loads. E. It provides Additional Safety for your maintenance personnel, giving to your system more Availability and Flexibility. ECOMODE CONFIGURATION Cost savings can be easily achieved by adopting our exclusive Ecomode configuration. Customer Values Ecomode in fact translates into a higher power factor which in turn means more savings. EcoMode: Less sensitive loads may be fed through the bypass static switch while the bypass mains is within an acceptable frequency and voltage window. Failure of the bypass mains to remain within this window results in transfer of your critical load to the Hipulse inverter. The rectifier/charger in either case float charges the battery system while its input mains is present. 8

9 3CONFIGURATION 3 A Hipulse system consists of either a single module unit, or of two or more (up to a maximum of six) units of the same kva rating. Systems with more than one module operate simultaneously in a parallel configuration with your critical load shared equally between the connected modules. With the exception of a single module configuration, the system will be redundant or non-redundant as per your need and requirement. Several system configurations are shown in the next pages. For more details on various configurations, please refer to your (nearest) Liebert Hiross sales (representative) office. A. Non-Redundant System: in a non redundant system all modules will supply your full rated load. If a module fails, the load will be transferred, automatically and uninterrupted, to the bypass line by the use of the static switch (for 1+N configuration) or the Main Static Switch (for Multi Module Units configuration). B. Redundant System: in a redundant system the system has one or more modules than the minimum required to supply your full rated load. Failure of one the modules will cause that module to be disconnected from your critical load and the remaining module(s) will continue to supply your load. Upon repair of the module, it will be reconnected to your critical load to resume redundant operation. Any Hipulse module is capable of being taken off your critical load manually for maintenance without disturbing your critical load bus. Module redundancy level is a predefined number of modules that are required to supply your full rated load. With the number of connected modules equal to this value, a failure of another module will cause your critical load to be transferred automatically and uninterrupted to the bypass line by the use of the static switch (for 1+N configuration) or the Main Static Switch (for Multi Module Units configuration). BASE UNIT UPS Single Module Hipulse consists of an appropriate number of single module units to meet capacity or redundancy requirement. Each UPS module consists of a rectifier/charger and three-phase inverter with associated transformer, static transfer output switch, static bypass switch, synchronizing equipment, protective devices and accessories as specified. Such Hipulse Module is called SMS (Single Module System). Each UPS module also includes an optional battery disconnect breaker and optional battery system.

10 3 UPS Multi Module The UPS system consists of an appropriate number of multi-module units for capacity and redundancy a Main Static Switch (MSS), battery disconnect breaker(s) and battery System(s). A. Each multi-module unit (MMU) consists of a rectifier/charger and three phase inverter with associated transformer, static transfer output switch, protective devices and accessories as specified. B. The MSS cabinet contains the main static switch (of bypass circuit), synchronizing equipment and maintenance bypass circuit. Normal Mains Q1 RECTIFIER DC BUS BATTERY CIRCUIT BREAKER INVERTER BATTERY STATIC SWITCH Q4 Hipulse Multi Module Unit (MMU) Crit ical Load Diagram 3 - Hipulse Multi Module Unit (MMU) SYSTEM CONFIGURATIONS Hot Stand-By In this configuration a couple of Single Module System (SMS) UPS can feed one or two load banks. As shown in diagram 4, the bypass mains of the first UPS (A) powering the critical load is supplied by the second one (B). In case of failure of UPS A, your critical load will be fed by UPS B output via the bypass line, in order to still guarantee all the Hipulse quality power features to your critical load. Furthermore, this System Architecture allows to supply also a possible normal load, increasing the flexibility of this kind of Configuration. As a matter of fact, Hot Stand-by solution is able to increase the reliability and the maintainability of your systems, even when an existing installation is concerned (it can be implemented regardless UPS size, generation and manufacturer). This can be possible for a couple of reason at least: this type of configuration can be realized by means of easy connections this type of configuration doesn't require interchange signals between UPS apparatus Customer Values This feature guarantees the quality power to your critical load even when a UPS has a failure. This configuration can be implemented even for existing installation. Enhanced Flexibility and Maintainability for You. Enhanced Reliability for your critical loads. 10

11 3 Normal Load + Priority Load UPS "B" Rating Normal Mains Bypass Mains UPS B BATTERY CIRCUIT BREAKER BATTERY Normal Mains UPS A Normal Load BATTERY CIRCUIT BREAKER BATTERY Priority load Diagram 4 - Hot Stand-by Configuration 1+N Without MSS (Main Static Switch) In this configuration every Hipulse is basically configured as being single module System (SMS) and no particular adjustments have to be done (see diagram 5). It is possible to implemented the System up to six modules in parallel. This implementation can be realized even for existing Hipulse UPS installations.the total load is of the single Hipulse UPS system (depending on the redundancy level) and it is going to be equally shared between all modules. When this type of system configuration includes more than two modules, Liebert Hiross suggests to install a Maintenance Bypass Cabinet; it allows to perform a very safe maintenance to your apparatus, giving you the possibility to remove any Hipulse module without affecting the normal system operation (depending on the redundancy level). "1+N without MSS" solution allows you to obtain: increasing of the system reliability, in order to ensure the presence of quality power for your crtical load increasing of the power availability following the power demand even it was not forecasted, in order to give you an enhanced flexibility for your critical load increasing of the maintainability, in order to perform routine maintenance or repair without affecting the normal system operation (depending on the redundancy level) Customer Values Single Module or 1+N. This option gives you the flexibility to scale the system only when you need to. Start with one or two modules and add more when you need more power or higher redundancy. Avoid immobilizing resources for an over dimensioned unit today. Maintenance Bypass Cabinet it allows to perform: a very safe maintenance to the apparatus the removing of one Hipulse module without affecting the normal system operation (depending on the redundancy level ). Enhanced Availability and Maintainability for You. 11

12 3 Bypass Mains Normal Mains Normal Mains Normal Mains UPS 1 UPS 2 UPS 6 Maint enance Bypass Cabinet Crit ical Load Diagram 5-1+N without MSS (Main Static Switch) Configuration Multi Module Units (MMU) With MSS (Main Static Switch) This feature allows you to have Hipulse in a parallel configuration with MMU (Multi Module Units), without the distribution of the bypass of each machine (see diagram 6). This configuration requires the MSS (Main Static Switch), which has to be sized depending on your critical load. It is possible to implement the System up to six modules in parallel. The total load is of the multi module Hipulse UPS System (depending on the redundancy level) and it is going to be equally shared between all modules. "Multi Module Units with MSS" solution allows you to obtain: increasing of the system reliability, in order to ensure the presence of quality power for your critical load increasing of the power availability up to the MSS capacity increasing of the maintainability, in order to perform routine maintenance or repair without affecting the normal system operation (depending on the redundancy level) centralised monitor of all system parameters (i.e total output current) Customer Values MMU with MSS. This feature allows you to expand the system when you really need to (up to six modules), depending on the size of your Main Static Switch (MSS). This configuration gives you another choice in configuring your system architecture, keeping all the benefits belonging to a parallel configuration. Enhanced Flexibility and Reliability for You. 12

13 3 Normal Mains Normal Mains Normal Mains Bypass Mains UPS 1 UPS 2 UPS 6 MSS Crit ical Load Diagram 6 - Multi Module Units (MMU) with MSS (Main Static Switch) Configuration Frequency Converter Hipulse is designed to function with the output AC to your critical load, supplied at a different frequency to the input mains. The following frequency conversions are available: Hz input 60 Hz output Hz input 50 Hz output When operating a single module as frequency converter the Hipulse requires the static bypass operation to be disabled and isolation of the input mains supply from your critical load. These modifications will be carried out by the setting of internal links to inhibit the static switch operation, and isolation of the supply to the bypass isolator. As a bypass is not required, it is easiest to implement a frequency converter application by using a Multi Module Unit version (MMU) Hipulse module (see Diagram 7). For requirements with different operating voltages the solution is to use a standard MMU module with external adapter auto-transformer. Customer Values This feature provides an additional value of an added application (as frequency converter) to customer's investment. 13

14 3 Normal Mains Q1 RECTIFIER DC BUS BATTERY CIRCUIT BREAKER INVERTER BATTERY STATIC SWITCH Q4 Hipulse Multi Module Unit (MMU) Crit ical Load Diagram 7 - Frequency Converter Configuration for MMU Dual Bus System A Dual Bus System supplies power to the loads from two independent sources (see diagram 8). This configuration will guarantee a very high level of reliability to your critical loads. The main frame of the power distribution is constituted by two different buses. Power can go through two different UPS systems, each consisting of 1 up to 6 UPS modules. These systems can be different in terms of power rating and redundancy. They can be also fed by two different distribution substation. Both bus power supplies are going to be kept in synchronism with each other by means of the HiSync Dual Bus Synchroniser (DBS), a special feature explained in the Optional Solutions chapter. Power coming from both buses can supply your "dual cord" load. HiSwitch has to be installed if you have to power your "single cord" load. This special feature is able to automatically transfer your critical load between the two sources in case of fault of one of them. This switching is performed without affecting the normal operation of your critical load. "Dual Bus System" allows you to phenomenally increase: the system reliability, in order to ensure the presence of quality power for your critical load the system maintainability, in order to perform routine maintenance or repair without affecting the normal system operation Customer Values Dual Bus System. This configuration allows you to ensure a very good quality power to your critical loads. As far as redundancy is concerned, a very high system reliability is guaranteed by using two power supply buses. Furthermore, this type of distributed system allows you to get a very high level of maintenance performances without affecting the normal system operation. Enhanced Reliability for You. Enhanced Flexibility for You. Enhanced Maintainability for You. 14

17 4COMPONENTS 4 RECTIFIER/CHARGER The term rectifier/charger denotes the solid-state equipment and controls necessary to convert AC to regulated DC for input to the inverter and for charging the battery. A. Input Current Total Harmonic Distortion: The available filters allow low THD values (as low as 4.0%), as shown in tables 4 and 11. B. AC Input Current Limiting: The rectifier/charger includes a circuit to limit AC input current to 125% of the full input current rating. A secondary circuit provides limiting to 100% on receipt of an external low voltage signal ( i.e. during generator operation). C. Battery Charge Current Limiting: The rectifier/charger includes a circuit to limit the battery charging current to 25% of the input power rating current. D. Battery Charge Compensation: The rectifier/charger automatically adjusts the battery float charging voltage by ± 2 mv per cell per C when used in conjunction with an optional remote temperature sensor. E. Input Power Walk-in: The rectifier/charger provides a feature that limits the total initial power requirements to 20% of rated load and gradually increases power up to 100% of full rating over a selectable time (2 or 10) second time interval. F. Input Isolator: The rectifier/charger has an input isolator and is fuse protected. The isolator is of the frame size to supply full rated load and recharge the battery at the same time and will withstand a short circuit current up to 100 ka rms. G. Fuse Protection: Each AC phase is individually fused with fast acting fuses so that loss of any semiconductor will not cause cascading failures. H. DC Filter: The rectifier/charger has an output filter to minimize ripple current into the battery. The AC ripple voltage of the rectifier DC output does not exceed 1% rms of the voltage float. The filter is adequate to ensure that the DC output of the rectifier/charger will meet the input requirements of the inverter without the battery connected. I. Battery recharge: In addition to supplying power to your critical load, the rectifier/charger is capable of producing battery charging current sufficient to replace 95% of the battery discharge power within ten (10) times the discharge period. This for batteries with back-up times up to approx. 1,5 h. After the battery is recharged, the rectifier/charger maintains the battery at full charge until the next emergency operation. Customer Values A. With lower input THD value, the customer gains in term of lower electricity bills and lower upstream power pollution. Such gains are really tangible for higher ranges of UPS (i.e. > 200 kva). Below that rating, it is not really worth mentioning. C-D. Such controls are valuable additional protections for the battery and its life duration. All the described features will phenomenally improve it. Investment Protection for You. E. As shown in the picture (fig. 2), the current smoothly follows the sudden voltage variation. The control on the current itself is extremely important and allows a very accurate power walk-in. H. Even a small AC component circulating in the battery will significantly heat it up and shorten its life. Hipulse is built with no compromises regarding the protection of all the components. Investment Protection for You. I. A significantly oversized rectifier is able to guarantee a good recharge time (10 times the discharge period) to the battery in every condition and will reduce the risk of having it not fully charged in case of need. It is able to guarantee as much as 25% of the nominal current dedicated to the battery recharge also at full load. 17

18 4 voltage current 2,5 sec Fig.2 Power Walk-in INVERTER The term inverter denotes the equipment and controls to convert DC from the rectifier/charger or battery to provide AC power to your critical load. The inverter is solid-state, capable of providing rated output power. For increased performance, the inverter is a Pulse Width Modulated (PWM) design and utilize Insulated Gate Bipolar Transistors (IGBTs), switching at high frequency in order to minimize output voltage distortion. A. Overload Capability: The inverter is able to sustain a power overload across its output terminals up to 150% with ± 2% output voltage regulation. In short circuit condition and without the bypass mains available the inverter is capable of supplying at least 150% current for a period up to 5 seconds, after that the Inverter is disconnected from the critical bus. B. Output Frequency: The inverter tracks the bypass mains continuously providing the bypass source maintains the rated frequency (of either 50 or 60 Hz) ±1 or ± 2% (selectable). The inverter will change its frequency at 0.1 Hz per second (adjustable 0.1 to 1.0 Hz per second) to maintain synchronous operation with the bypass. This allows make-before-break manual or automatic transfers of your critical load between the inverter and the bypass mains. If the bypass mains frequency falls outside of these limits, the inverter reverts to an internal oscillator which is temperature compensated and hold the inverter output frequency to within ± 0.01 Hz of the rated frequency for steady state and transient conditions. Drift does not exceed 0.1% during any 24 hour period. Total frequency deviation, including short time fluctuations and drift, does not exceed 0.1 Hz from the rated frequency. C. Phase-to-Phase Balance: System logic provides individual phase voltage compensation to obtain phase balance ± 1% under all conditions including up to 100% load unbalance. D. Fault Sensing and Isolation: Fault sensing is provided to isolate a fault inverter from your critical load bus to prevent disturbance of the critical load voltage beyond the specified limits. The inverter output static switch gets switched off to isolate a fault module from your critical load. E. Battery Protection: The inverter is provided with monitoring and control circuits to protect your battery system from damage due to excessive discharge. Shutdown of the inverter is initiated when the battery has reached the end of discharge (EOD) voltage. The battery EOD voltage is calculated and automatically adjusted for reduced load conditions to allow for extended autonomy periods without damage to your battery. Automatic shutdown control will not be a function of discharge time. 18

19 4 Customer Values IGBT: This feature allows inverter to switch higher currents at higher frequency. Low current dissipation. Best system efficiency. Investment Protection for You. Customer Values A. High overload capability (current overload at nominal voltage) allows the customer to avoid the UPS oversizing and let the UPS absorb basically peak power requirement for a specified duration to enhance availability. Reduced initial investment for You. B. The possibility to modify the behavior of the UPS according to the frequency fluctuations value, makes the UPS extremely flexible (it can be used as a frequency converter as well). User flexibility for You. C. This lets you distribute the load between the phases absolutely as you require to do, without any worry for UPS or balancing the loads. User flexibility for You. D. This feature allows to avoid damaging for your critical load. Investment Protection for You. E. This feature offers an extra protection to your battery preventing dangerous situations that could seriously damage it. Investment Protection for You. Fig kva Hipulse 19

20 4 STATIC BYPASS Static Bypass (Single Module Only) For time when maintenance is required or when the inverter cannot maintain voltage to your critical load due to sustained overload, current limiting or failure, a bypass circuit is provided for each module that forms part of the UPS system. The modular bypass circuit(s) will provide for isolation of the inverter(s) and provide a path for power directly from an alternate AC (bypass) source. The UPS control constantly monitors the availability of the inverter bypass circuit to perform a transfer. The inverter bypass of each module consists of a static transfer switch, operating in conjunction with the inverter output static switch. The static switches denotes the solid-state devices that, operating simultaneously, can instantaneously connect your critical load to the alternate AC source. MAIN STATIC SWITCH (MSS): APPLICABLE FOR MULTI MODULE UNIT (MMU) ONLY Bypass Mains Q1 From UPS MSS Diagram 9 - Main Static Switch (MSS) Q3 Crit ical Load Q2 20

21 4 The UPS system is provided with a separate free-standing bypass main static switch for time when maintenance is required or when the inverter cannot maintain voltage to your critical load due to sustained overload, current limiting or failure. The MSS static bypass circuit provides for isolation of the inverter(s) and provides a path for power directly from an alternate AC (bypass) source. The UPS control constantly monitors the availability of the inverter bypass circuit to perform a transfer. The static switch of MSS operates in conjunction with the inverter output static switch. The static switches denote the solid-state devices that, operating simultaneously, can instantaneously connect your critical load to the alternate AC source. A. Manual Load Transfers: A manual load transfer between the inverter output and the alternate AC source is initiated from the control panel. A means to perform manual transfers remotely is made available as an optional extra. B. Automatic Load Transfers: An automatic load transfer between the inverter output and the alternate AC source is initiated if an overload or short circuit condition is sustained for a period in excess of the inverter output capability or due to a failure that would affect output voltage. Transfers caused by overloads will initiate an automatic retransfer of your critical load back to the inverter only after your load has returned to a level within the rating of the inverter source. C. Back-feed Protection: The static bypass is provided with detection and control circuits, to be used in conjunction with external automatic switch-gear, in order to disconnect the bypass line in the event of a short-circuit being detected in the solid-state devices that form the bypass static transfer switch. The purpose of this requirement is to prevent the risk of electrical shock on your distribution system when the normal source of power is disconnected or has failed. Customer Values A It allows to choose how supplying your critical load, depending on your need. Enhanced Availability and Flexibility for your critical load. B It allows to protect either your UPS or your critical load in case of output failure. Investment Protection for You. C Back-feed protection system is an important extra safety tool to protect the life of everyone working on the machine, guaranteeing you also in case of an internal short circuit. This feature permits a very safe manual operation on every condition. Additional Safety and Investment Protection for You.

The Hipulse chassis has an equipment earth terminal. Provisions for local bonding are to be provided. INSTALLATION Mechanical Considerations Hipulse system can comprise a number of equipment cabinets, depending on the individual system design requirements. In general, all the Hipulse cabinets used in a particular installation are of the same height and designed to be positioned side-by-side to form an aesthetically appealing equipment suit. As Hipulse has no ventilation grills at either the sides or the rear, no clearances are required. Back-access is not an essential requirement for maintenance: however, where space permits, a clearance of approximately 600 mm will ease access to magnetic component parts. Clearance around the front of the equipment should be sufficient to enable free passage of your personnel with the doors fully opened.cables can enter for Hipulse cabinet either from below or through either side. Side entry is made possible by removing blanking pieces fitted in the side panel to reveal the cable entry holes. This cable entry method allows the equipment to be positioned on a solid floor without the need for cable trenching and allows cables to pass from one module to the other when positioned side-by-side. Optionally a top cable entry extension may be used ( for more details see Optional Solutions chapter). Customer Values Modular design of cabinets. It allows You to obtain Enhanced Scalability to your System. No clearance. Space Saving, Low Cost of Ownership for You. Cable entrance. Easier access and arrangement for your connections means easier maintenance and a safer environment. 28

29 5 Electrical Installation Hipulse requires both "power" and "control" cabling once it has been mechanically installed. All "control" cables, whether screened or not, should be run separate from the power cables in metal ducts which are electrically bonded to the metalwork of the cabinets to which they are connected. The rectifier input, bypass, output and battery power cables (all require lug type terminations) are connected to bus bars situated in the bottom side of the cabinets. Terminal blocks are used for connecting the control cables to the battery circuit breaker, external emergency stop facility, external OFF inverter, external Bypass, etc. The safety earth bus bar is located near the input and output power supply connections. Customer values Bus bars and terminal blocks. This feature allows to reach a User Friendly access and arrangement. "Control" and "Power" cables. They have been designed to follow different paths inside Hipulse, in order to eliminate disturbance inducted by "power" cables. Enhanced Reliability and Availability to your System. TECHNICAL DATA General Notes There are some UPS parameters (e.g. Input current THD, Efficiency, etc.) that could be influenced by your application and/or environmental conditions. In fact, a mix of circumstances as mains impedance level, harmonic pollution caused by power electronics based equipment, the different quality of power generators, transmission lines, substations, distribution lines (due to the different utility companies), loading conditions like % loading, nature of load, characteristics of the load, starting behavior of the load, number of start/stop per day etc. make it difficult to state the exact data for these above parameters of the UPS after its installation. All these factors have led our Engineering & Development Department to be more prudent in data declaration. The data available on Hipulse Guide are the close-to-accurate values. We suggest you to please contact our nearest sales office/representative in order to get more relevant data related to your plant and application in particular. 29

45 7OPTIONAL SOLUTION 7 To further improve the quality of your power quality solution, Hipulse units can be coupled with several optional components. Some of these will enhance your control of the system, some will make the installation easier, while some other will increase the level of protection of your applications. All can significantly add to a Hipulse system and suit your needs of a complete Power Quality Solution. The benefits and applications of each will be clarified in the following paragraphs, however, you can confidently refer to any Liebert or Liebert Hiross representative should you need further explanation about each of the following solutions. Optional components fall broadly under three categories: communications solutions power reliability solutions additional components Below is a brief description of all of them. COMMUNICATIONS SOLUTIONS Monitoring And Shutdown Software HiLink UPS Monitor HiLink UPS Monitor is a cost effective supervision software that will monitor all status, alarm and metered information at the Hipulse UPS. The information is displayed on the computer monitor as a live copy of the UPS display mimic, or can be made available as a data log file. Log files can be further exported in common spreadsheet and database formats for charting and trending. HiLink UPS Monitor allows monitoring not only of single UPS units, but of a whole system. A system can be composed up to 6 UPS units and 1 optional MSS. Only one connection with the server is needed in this case. The software can be further coupled with a Remote Control Panel (see below) for extra flexibility. For remote monitoring one modem connected to a telephone line is required per system this means that each installation, composed of up to 6 units plus MSS will share one modem and one telephone line only, therefore saving connection and setup costs. On a TCP/IP or dial-up network, information can be displayed also on remote computers, and status messages and alarms can be sent via or to out-of-band devices such as pagers or SMS compatible mobile phones. HiLink UPS Monitor runs on Microsoft Windows 95/98/NT4/2000 platforms. When used in combination with MultiLink 3 the software will allow cross platform shutdown of servers and workstations.

52 7 Input Filter Properly designed tuned filters are available to reduce the most critical harmonic pollution (5th and 11th). They also can improve the Hipulse input power factor, leading Power Factor (P.F.) from 0,8 up to 0,93. These input filters can be installed without any additional system footprint and their performances are shown in tables 4 & 11. Input Isolation Transformer Input Isolation Transformers are required in case of having a galvanic isolation between Input/Bypass Mains and UPS Output. They are normally a Delta/ZigZag double wound transformer and they are available for every range of UPS ( kva). They are housed in an optional cabinet in which the nonautomatic circuit breaker with fuses are also installed. Input isolation transformer are designed to power both rectifier and bypass mains, depending on their size. Transient Voltage Surge Suppressor - TVSS This option is an advanced Transient Voltage Surge Suppressor. It has been designed for medium and heavy duty applications with capacities from 100 up to 400 ka per phase. TVSS is normally connected at the bypass path of Hipulse or inside the HiSwitch as an optional item. Customer Values Input Filter Lower cost of ownership, due to lower electricity bill and reduced up-stream power pollution. Input Isolation Transformer Enhanced optional protection: Galvanic Isolation Reduced Fault Current Reduce the harmonic currents back on mains when the UPS is on bypass Protection (optional) against Battery Ground Fault Creation of Neutral Top Cable Entry It is possible to have a top cable entry option when the power supply cables are coming from the top of UPS. This kit incorporates a bus bar cabling system and flexible cables to connect to the Hipulse input/output terminals. This option is available for a wide range of Hipulse UPS ratings. Battery Circuit Breaker (BCB) Each Hipulse UPS module has the optional properly rated circuit breaker (500 Vdc) to isolate it from your battery. This breaker is to be housed in a separate enclosure, or mounted inside an optional battery cabinet. When the BCB is open, there will be no battery voltage inside the Hipulse enclosure. Each Hipulse module will automatically be disconnected from your battery by opening its breaker when it reaches the minimum discharge voltage level or when signaled by other control functions. 1+N Parallel Interface Kit This kit allows UPS modules to operate in parallel mode, with SMS (Single Module System) without the use of MSS (Main Static Switch). Battery Ground Fault Sensor This option allows to detect a battery ground fault; it gives an alarm contact output that can be managed by your system. 52

61 12 VALUES DECLARATION NOTES 12 When anyone is requested to provide any kind of parameter, he will find out that there are many ways to proceed and statistical interpretation. How does this process and the value distribution work? The desired values are spread between a minimum and a maximum (see graph 1 as an example of efficiency measurement) but are mainly concentrated near a mean value which will be the most common one. The standard deviation (shown in graph 1) is a value that is mathematically calculated in order to give information about the event's distribution percentage and strictly linked with the shape of the Gauss-bell. A rigorous declaration of a value should consist of the mean value and the standard deviation value, in order to allow the customer to draw the Gauss-bell curve and have a clear view of the situation. Graph 1 What does Liebert Hiross do? We are actually very conservative regarding the affirmation of the performances of our UPS and the values we declare are realistic as being the minimum ones (see left-hand side arrow in the curve) at the left of the standard deviation value. This allows us to state: the efficiency will be not less than..% without any tolerance. Why have we chosen such a solution? Because for the customer it s extremely difficult to assess if the claimed value is really true or the result of a generous tolerance. He should, in fact, test hundreds of machines to realize that standard deviation value or the mean one is not correct. The only way to ensure the quality and the performances of a machine is actually to assure a minimum value, that the customer will be able to consider good enough, according to his needs. Come to visit us and attend a witness test, we will be glad to show you our factory and products! 61
