Power Meter I-LEM Package Connections

NOTE: Refer to the bulletins shipped with each component and included in the I-Line Enable Module installation packet for detailed set-up instructions.

Install the power meter shorting block (included in package), according to the instructions provided, prior to installing the Power Meter I-Line Enable Module.
Install Power Meter I-Line Enable Module according to the I-Line Enable Module installation instructions.
When connecting the CTs to the shorting block of the Power Meter I-Line Enable Module, note that typically "X1"="White"="+" and "X2"="Black"="-". However, refer to the CT manufacturer’s specifications for the exact nomenclature equivalent to primary "X1" and secondary "X2."
If the system uses an alarm output or additional inputs, connect to the appropriate Input/Output terminals on the accessory panel of the Power Meter I-Line Enable Module identified as X = D1/D2 (Outputs) and Y =S1/S2 (Inputs).
If the voltage system requires a neutral, a connection must be made from the panelboard neutral to the terminal identified as "VN" on the accessory panel in the Power Meter I-Line Enable Module.
Connect the Ethernet cable to the RJ45 socket connector labeled "ETHER 1" on the accessory panel for remote set-up or monitoring of the Power Meter I-Line Enable Module.

Optional: A second Ethernet RJ45 connection, labeled "ETHER 2," is available for daisy chaining additional Power Meter I-Line Enable Modules, or for daisy chaining Ethernet communicating equipment.

Refer to Power Meter I-LEM Communication Schematic Diagram and Metering Packages - Installation Schematics.
If communicating circuit breakers are present in the same system with the Power Meter, they are interconnected to the communication system via an IFM I-Line Enable Module in conjunction with a U-PaS I-Line Enable Module.

Connect the Ethernet cable to the RJ45 connector (labeled "ETHER 1") on the accessory panel of the Power Meter I-Line Enable Module and to the RJ45 connector (labeled "ETHER 2") on the U-PaS I-Line Enable Module to daisy chain the two devices.

Connect the Ethernet cable to the RJ45 connector labeled "ETHER 1" on the U-PaS accessory panel for remote set-up or monitoring of the network.

Connect the Modbus Serial cable to the RJ45 connector labeled "RS-485" on the U-PaS accessory panel for daisy chaining an IFM I-Line Enable Module. This connection allows the system to feature ULP connections to provide communication to communicating circuit breakers.

Refer to Power Meter I-LEM Communication Schematic Diagram, Power Meter I-LEM with Communicating Circuit Breakers Communication Schematic Diagram, and Metering Packages - Installation Schematics.
