settings
*1:Connect a power source for
the control circuit.
*2:The inverter is shipped with
the terminals PO and PA
shorted with a bar. Remove
this shorting bar and
install a DC reactor (DCL).
*3:Power output for the control
circuit, which is provided
only for the 400V 37kW
and larger models.

*4: Connections of control power cables by voltage for the
400V 37kW and larger models.
*5: For easy maintenance and inspection, connect the control power terminals RO and SO to the primary side of the MC in the main
circuit so that the control panel can be checked if only the control circuit is energized.
