Terminal symbol
A negative potential terminal of the internal dc main circuit. This terminal can be used to
PC
connect a dc common power source in conjunction with the terminal PA (positive
potential).
Used to connect a DC reactor (DCL: external option). The inverter is shipped with these
PO, PA
terminals shorted.
Used to connect the control output cables. Provided only for the 400V class 45kW and
larger models. (10VA)
