• To verify the proper wiring for a 4-wire PDCA, use a DVM to measure the voltage at the in-line connector.
Voltage should read 200 - 240 Vac phase-to-phase as measured between the connector pins as follows: L1
to L2, L2 to L3, L1 to L3.
• To verify the proper wiring for a 5-wire PDCA, use a DVM to measure the voltage at the connector.
Voltage should read 200 - 240 Vac phase-to-neutral as measured between the connector pins as follows: L1
to N, L2 to N, L3 to N.
