Wiring CTs
1. Attach the CTs onto the green connectors labeled CT1, CT2, and CT3.
2. Place the CTs on the phase wires of the load to be monitored, and corresponding
to the phase of the voltage leads. The CT labeled CT1 must be placed on the L1
phase voltage load wire, CT2 must be placed on the L2 voltage load wire, and CT3
must be placed on the L3 voltage load wire.
3. See
Checking Phases, later in this section for information about the CT LEDs and
how to verify the CT installation.
