Installing the Meter

Using the screws provided in the meter kit, attach the mounting plate to the inside of the main distribution board or to another surface. Choose a location that takes into account the voltage line harness and CT cable lengths.

Wire the Voltage Taps

  1. Plug the voltage line harness into the meter.
  2. Connect the voltage line harness leads to a dedicated two-pole circuit breaker (not exceeding 20 A) of corresponding phase inside the distribution board:
Voltage Harness Port/Wire Color Distribution Board Connection
A / Black L1 breaker terminal
B / Red L2 breaker terminal
C / Blue Spliced with the Red B wire
N / White Neutral busbar

Note
If a dedicated circuit breaker is not available, the voltage line harness can be spliced to existing breakers.

Install the Antenna

To install the antenna, screw it onto the meter. It is recommended to locate the antenna outside the enclosure using the included antenna extension:

  • Locate a 1/2” or 3/4" knockout and install a cable gland.
  • Mount the antenna by threading the extension cable through the included knockout mount and securing the mount.
  • Screw the antenna onto the extension cable and connect the extension cable to the meter.

Locate the CTs

  • Place a CT on the corresponding power wire in the main distribution board after the utility meter and ahead of any loads. Be sure to orient the CTs with the “source this side” text facing the utility source.
  • Connect the CTs to the ports on the remote energy meter. Ensure the CTs are connected to the correct CT ports on the meter.
