Each Meter ase can be connected to up to four Meter Modules in either a Strip or External configuration. The Meter Module Strips come in configurations of 9, 15, or 21 onboard current transformers (Ts) with terminals for up to four X auxiliary 333mV Ts. The Meter Module External supports the same number of load circuits; however, they are all external 333mV Ts. ll of the loads for each Meter Module must share a common mains Voltage connection. Meter Module Strips are mounted on each side of a panel board, beside the breakers, and can monitor current for both both three phase and single phase branch circuits. onductors pass through the onboard Ts before connecting to the breakers. The Meter Modules can also monitor voltage in the following configurations: Three Phase, four wire wye Three phase, three wire delta Three phase, center tapped delta Three phase, three wire Single phase, two wire The PXM-M has a built-in web server and an Ethernet port, making for easy configuration through a familiar web interface. Through the web interface you can designate whether breakers for each meter module are wired in a sequential, alternating, or custom configuration. You can also set up virtual meters, combining data from one, two, or three different phases into a energy meter. You can designate one of these virtual meters as the main. I150003E Page 2

6 Product Overview PXM-M Meter ase You can use the L port to connect the PXM-M to your L. The PXM-M supports both a fixed IP address and DHP. Once on the L, you can access the web interface for real-time energy, power, current, and voltage information. Device configuration is done using the web interface. The L port also provides a Modubus TP connection. The OM1 port is a serial RS485 Modbus RTU interface to support a local Display or for related monitoring purposes. n optional PXM-DISP-6 local display is available. You can connect the PXM to a building management system or other upstream monitoring software using either the Modbus RTU (OM1) or Modbus TP (L) interface. To preserve your settings, in case you must either replace a PXM-M or reset it to factory settings, you can save all of your configuration information to a file. onfiguration files can be uploaded to the PXM-M. If you re configuring multiple identical PXM systems, you can set up a single configuration file and upload this to multiple PXM-Ms. The M may either be factory mounted in a panel board or with the MME in an appropriate separate enclosure. The MME can be mounted in approved panel boards. The MMS can only be mounted in UL approved panel boards or appropriate separate enclosures. through the RS485 OM1 Modbus port using the RS-485 RTU protocol, or the L Modbus TP connection, or view it directly through the onboard web server. The M is powered through a single-phase connection to the panel mains. The power connection (marked Power Supply on the M) must be equipped with both a fuse block and disconnect switch. The Modbus address is set through a pair of rotary switches (ddress H-L) on the front of the PXM-M housing. Indicator lights show device status (Status) as well as communications status for both Ethernet (OM Status) and Modbus (om1 TX/RX). Indicators show the data Rx/Tx transfer activity. PXM-MMS Meter Module Strips Meter Module Strips (PXM-MMS) are available in configurations to mount on either the left or right of a panel board and contain 9, 15, or 21 Ts. Four additional connections are provided for X uxiliary T connections, which can be used to monitor the panel mains or branch circuits. The MMS has both load current and voltage metering circuits providing meter data to the Meter ase. Power must be supplied via the PXM-MMP-L cable for the Meter Module to operate. PXM- MMS - left PXM-M Meter ase The PXM-M is the data acquisition module of the PXM system. The PXM-M aggregates the data channels from the PXM- MMS and from the PXM-MME. You can access the data from all channels (including virtual meters) PXM-M I150003E Page 3

7 Product Overview PXM-MME Meter Module External PXM-MME Meter Module External Designed primarily for retrofit or high mix panel board applications, the MME provides connections for up to 25 external Ts as well as voltage measurement capability. Like the PXM-MMS, the PXM-MMP-L-nn cable provides both a data connection to the PXM-M and power to the PXM-MME from the PXM-M. The M mounts directly to the face of the MME using two #8-32 x 0.5 in screws, as shown in the following figure. The bottom figure shows the devices in the stacked configuration. PXM-M mounts on the PXM-MME with two #8-32 x 0.5 in screws. PXM-MME For retrofit applications the MME must be housed in an appropriate enclosure adjacent to the existing panel board or similar power distribution assembly. The Meter ase can share this enclosure. The MME can also be used in approved panel boards where a high mix of breakers does not fit the MMS. The Meter Module Ports support a maximum distance of 28 ft between the Meter ase and a Meter Module. For shipping split or similar reasons this MMP cable can be split in two sections using the PXM-MMP-LE cable extension in either 8 or 16 ft lengths. Stacking the PXM-M and PXM-MME The PXM-M and PXM-MME in the stacked configuration. If you re using the PXM-MME and mounting it in the same factory mounted assemblies as the PXM-M, you can mount the M directly to the MME to save space. I150003E Page 4

DETH, SEVERE PERSOL IJURY, OR SUSTTIL PROPERTY DMGE RESULT. For commissioning or debugging purposes, with the monitored power distribution assembly mains power shut down and locked out, it is possible for trained personal to temporarily apply power to just the PXM meter system. In panel board applications this assembly shut down would allow the panel trim to be removed for access to the PXM. y applying power from an external source to just the PXM-M Power Supply terminal, all of the electronics of the PXM-M and the Meter Module Port connected PXM-MMS and PXM- ME can be energized. The normal connections to the PXM-M Power Supply must be disconnected during this process. The metering values will be zeroed; however, all of the switches, LED indicators, and communication functionality will be accessible and active. This approach can be useful to configure and verify many of the details required for proper commissioning of the PXM. fter completion of this review, return the PXM Meter ase Power supply connections to the normal fuse and disconnect switch connections. When the overall assembly gear commissioning is complete and system power is applied, access to the PXM will be limited to communications from cables routed out of the assembly. Mounting and Wiring the PXM-MME Meter Module External The PXM-MME provides the same functionality as the PXM- MMS for retrofit or non-uniform/high-mix load applications. Unlike the PXM-MMS, the PXM-MME relies entirely on external Ts. These can be either solid or split-core 333mV Ts, which can be easily attached to existing panel wiring. Mounting The PXM-MME must be housed in an appropriate EM or UL enclosure that ensures the device will remain with its specified environmental ranges and provides fire and mechanical protection. In retrofit applications the MME must be mounted in an enclosure external from the monitored assembly gear, only the Ts should be within the existing panel unless the MME is an approved accessory for the assembly.

30 Glossary Glossary pproved Panel oard - pplication appropriate UL or EM approved electrical panel to enclose the PXM components, current sensors, and circuit breakers. ranch ircuits - Monitored loads whose wiring is protected by circuit breakers within a panel. urrent Sensor - External current monitoring circuit. In the context of the PXM, the current sensor consists of a urrent Transformer and burden resistor that results in a 333mV full-scale output when rated current is applied to the sensor. T - urrent Transformer. lso, T (urrent Terminal) is labelled on a device terminal block. Disconnect Switch - Load breaking switch or circuit breaker to safely separate equipment from line voltage for maintenance. Enclosure - ox to safely mount and hold electrical circuits and hardware. Main - Voltage source for one of more switchboard or panelboard circuits, commonly at the point of common coupling with an electrical utility. Modbus RTU - RS485-based serial communications protocol with a single master and one or more Remote Terminal Unit (RTU) devices. Modbus TP - Ethernet-based implementation of the Modbus protocol. Panel oard - Electrical power distribution assembly that sources power and provides over current protection to external loads. Panel boards are typically covered by UL67 for safety purposes. The PXM components are considered panel board accessories and must be approved for use within specific vendor panel board models. I150003E Pollution Degree - Level of environmental exposure for expected applications. PT - Potential Transformer (aka VT - Voltage Transformer). RS485 - Serial communication hardware physical layer interface using differential transceivers on a single twisted wire pair and common. Single-Phase - The voltage source is from one supply. Single-Phase, Three Wire - The voltage source is split at a transformer so that two wires have opposite polarity (180 degrees out of phase with each other) and one neutral wire is common. Single-Phase, Two Wire - The voltage source has one wire and one neutral. Three-Phase - voltage source with three wires that are out of phase with respect to each other Three-Phase Four Wire Wye - voltage source with a common neutral and three wires whose phases are 120 degrees apart with respect to each other. Three-Phase Three Wire Delta - voltage source with three wires whose phases are 120 degrees apart with respect to each other but without a wired neutral (ote: The PXM does not support a floating delta or a corner-grounded delta. The PXM specifically supports a delta circuit that comes from a Wye secondary transformer where the neutral is grounded but not made available to load circuits). Three-Phase enter Tapped Delta - (aka high-leg delta, hot-leg delta, wild-leg delta) Three-phase circuit with a neutral that splits one of three line-to-line voltages. s a result two of three line-toneutral voltages are of opposite polarity and a third voltage is larger and 90 degrees out of phase with respect to the other two line-to-neutral voltages. (ote: The PXM specifically supports the circuit where phase is the larger voltage.) Page 27

31 Glossary Power Xpert ranch ircuit Monitor: Meter Module Strip Virtual Meter One, two, or three current sensors selected and configured as an energy meter. In the context of the PXM, all selected sensors must be from the same meter module (MMS/ MME) for a given virtual meter. I150003E Page 28
