10 WIRELESS NETWORK 10 Features RF Specification The sentinel all-inclusive monitor and transceiver make for an easy install without the need of multiple devices. The sentinel all-inclusive monitor is also a functioning standalone kwh meter. The sentinel comes standard with up to 2 inputs that integrate existing installations to wireless. The sentinel can upgrade from a standard monitor to a wireless mesh network protocol The sentinel supports RF line-of-sight range up to 28 miles outdoors, using a high gain directional antenna. The sentinel stays idle at 63mW(+18dBm) rate at 250kbps to minimize power consumption. Each monitor is FCC certified to limit interference with existing networks.

11 The sentinel operates on a license-free frequency band at 2.4 GHz. 11 WIRELESS BASE STATION Includes Field commissioning Software USB Ethernet connection SMA/NMALE cable NMALE/NMALE antenna cable Flat panel antenna Nu-Core and Software Features The Nu-Core acquisition system is a gateway to the sentinel monitors and the base station software on the PC. The Nu-Core supports sentinel devices in the same network. Wireless Operation The sentinel network interfaces with the Nu-Core acquisition system and transmits kwh data consumption, water consumption and potential current to ground. The base station software collects and stores data from the Nu-Core acquisition system. The data is accessible in a text file that updates the user s remote billing database to generate customer profile and billing.

12 12 IIM INSTALLATION INSTRUCTION WARNING: BEFORE INSTALLING OR WORKING ON ANY ELECTRICAL EQUIPMENT READ THE INSTALLATION INSTRUCTION IN ITS ENTIRETY. ONLY QUALIFIED ELECTRICIANS OR CONTRACTORS FAMILIAR WITH THE CONSTRUCTION AND OPERATION OF THIS KWH MONITOR SHOULD INSTALL THIS EQUIPMENT OR ANY ELECTRICAL DEVICE. INSTALLATION SHOULD BE DONE IN ACCORDANCE WITH LOCAL AND NATIONAL ELECTRIC CODES. Planning the Installation of the Monitor in Power Outlet Fittings or Panel Boards List of materials and tools required KH-series kwh monitor with CTs Line voltage 4 or 8 pin connector with 18 AWG 105 C 300 volt conductors Line current/dc 10 or 20 pin connector with 20 AWG 105 C 300 volt conductors 12volt DC electromechanical counter Multi-meter, screw driver (Phillips and/or slotted), electrical tape, tie wraps, heat gun and screws DISCONNECT POWER FROM THE POWER OUTLET FITTING Caution: Do not use the breaker in the power outlet fitting as a disconnecting means. Disconnect must be made at the main panel or safety switch. If there is more than one disconnect servicing the equipment disconnect both supplies before servicing the equipment. Caution: Using a Multi-meter, check the conductors supplying power to the power outlet for any sign of voltage. This can also be done at the receptacles at the power outlet.

13 13 IIM INSTALL MONITORING COMPONENTS Note: Refer to the manufacturer s instruction manual on the power outlet. Use the required tools to gain access into the power outlet. MOUNTING THE kwh MONITOR Find the manufacturer s recommended location inside the power outlet to mount the kwh monitor. With the #4 or #6 screws provided, mount the kwh monitor as shown in Figure 1 using option 1 or 2. FIGURE 1 INSTALLATION INSTRUCTION MOUNTING THE COUNTERS (optional when counter is not provided in power outlet or panel boards) Locate the counter s 1/8 mounting holes for panel mount counters and/or rectangle holes for snap-in counters Disconnect the counter from the current supply wire harness Mount the counter with two #4 screws provided into the power outlet. Refer to Figure 2 Reading your counter When using a snap- in counter, feed the counter conductors through the power outlet panel from the outside. Refer to Figure 2. The counter Requires a 12volt supply from the monitor the counter displays 6 digits, the 5 digits from left to right displays kwh And the first digit to the right displays a 10 th of a Kwh. Example: When counter displays kwh use the first 5 digits then subtract the last meter reading 01234kwh from the current meter reading 12345kwh and multiply by the cost kwh = $0.12, 12345Kwh 01234Kwh= 11,111kwh x $0.12= $1, total cost.

15 15 IIM INSTALLATION INSTRUCTION INSTALLING MONITOR S CURRENT SUPPLY WIRE HARNESS Locate the conductors coming from the load side of the breaker and the neutral conductor feeding the receptacle in the power outlet or panel board. Disconnect the conductors from the receptacle or the line conductor from the breaker coming from the bus bar assembly. Place the current sensor between the breaker and receptacle or between the breaker and the bus bar assembly in the power outlet. When placing a monitor in a panel board multiple current sensors can be used on the load side of the branch breakers to be monitored. In a case where one monitor is required, current sensors shall be mounted on the line side of the main breaker or main lug when provided. Feed the load or line lead through the current sensor. (Note: the current sensor is nondirectional; it will function in any direction.) It is important to pay attention to the phasing; if there is more than one pole or phase that will be monitored, i.e. receptacle or breaker in the circuit, only the conductor connected to the same line voltage shall feed through that current sensor. Refer to Figures 3-6 and pages 7 & 8 of the wire harness assembly detail in this manual. INSTALLING MONITOR S VOLTAGE SUPPLY WIRE HARNESS Connect the 18 AWG 105 C 300-volt wire from the kwh monitor voltage conductor (black, red or blue) to the line side of breaker or to the bus bar assembly. Connect the 18 AWG 105 C 300-volt white conductor to the neutral line at the bus bar or to the nearest neutral conductor.

16 16 IIM CHECKING INSTALLATION Reconnect the gray conductors to the counter with the quick disconnect. Check all conductors for loose connections. Turn power back to the on position, then check that the power LED is on. Note: if the meter does not function do to power outage disconnect power harness From the meter for 10min. and reconnect. The power LED will illuminate. If not Disconnect again for additional 30min. the meter will reboot. Note that when power is applied to the monitor the load LED will flash. Apply a 1500watt load with a heat gun or equivalent for 5 minutes. Within 2 to 5 minutes the load LED will flash, indicating a successful installation. Ground Fault Check Optional Red LED The red LED turns on when a fault exceeds the dip switch set point in the meter. Once the fault clears the LED will turn off after 24hr. Note: if the meter does not respond by not turning back on after a surge or fault a hard start is recommended by disconnecting power from the meter and applying power back to the meter.
