Overview of switch operation
■
Operating the WIRING switch
When the MAIN POWER switch is turned ON, the WIRING switch is always set to
1P (single-phase). Press the desired button for the WIRING switch, then turn the
SYSTEM POWER switch ON. Once the SYSTEM POWER switch is turned ON,
operation of the WIRING switch is disabled. This feature is intended to prevent out-
put switching in the power-supplied status.
POWER switches on the PCR-LA power supplies
All of the PCR-LA AC power supplies’ POWER switches must be turned ON in
advance. For more information, see “2.6 Power ON”.

System operation method
The WIRING switch determines the operation method of the output-switching sys-
tem, including the PCR-LA power supplies. When 1P is selected, the PCR-LA
power supplies perform single-phase parallel operations. When 1P3W is selected,
they perform single-phase, three-wire output operation.
