*1: Some inverters* are shipped with the PO and PA/+ terminals short-circuited with a shorting bar. (* 200V/45kW
class and lower and 400V/75kW class and lower)
*2: To back up the inverter’s internal power supply that supplies control power, an external control power backup
device (CPS002Z - optional) is required. The optional control power backup device can be used with both 200V
and 400V classes.
*3: By default, the FL relay is set as a failure FL output relay.
