2-phase 3-wire connection with two CTs

Direct voltage connections for the input voltages L-L up to 480 VAC.

Otherwise, two PTs

Figure 5-6: 2-phase 3-wire connection

NOTE: Make sure 2-phase is programmed in the power meter PROG menu- setup.

Single-phase connection with 1 CT

Direct voltage connections for voltages up to 480 VAC LL. Otherwise, use

one PT.

1. Program the power meter in single-phase mode.

However, voltages primary and secondary need to be programmed as

Line to Line.

2. Connect the voltage and current inputs only to the V1 and A1 voltage

and current terminals of the power meter.

3. The unused current terminals (A2 and A3) must be shorted together to

reduce noise picked up in the power meter.

4. However, the energy parameter readings will be accurate.
