Figure 10. PM3 Breaker Status Wiring Diagram (KD/LG PM3).

Breaker Status:

Breaker status is brought to the unit through a 5-pin Phoenix

RA-series connector, part number 1844249. Figure 10 shows the pin

assignments for this connector.



CAUTION

FOR WYE SYSTEM, A NEUTRAL IS REQUIRED TO BE CONNECTED TO THE

PM3 ON THE RIGHT PHOENIX CONNECTOR. IF NEUTRAL IS NOT AVAIL-

ABLE, THE METER WILL CALCULATE A VIRTUAL NEUTRAL BASED ON THE

PHASE-TO-PHASE RMS VOLTAGE. THE SYSTEM MUST BE BALANCED FOR

THIS TO BE ACCURATE.
