The figure below shows an example of typical wiring in the main circuit of a 200V 0.4-75kW/400V 0.75-160kW inverter.
Main circuit power source
200V class:
0.4~45kW Three-phase 200~240V-50/60Hz
55kW, 75kW Three-phase 200~220V-50Hz
Three-phase 200~240V-60Hz

*1: The inverter is shipped with the terminals PO and PA shorted with a bar (200V-45kW or smaller, 400V-75kW or
smaller). Remove this shorting bar when installing a DC reactor (DCL). Be sure to connect the DC reactor for the
200V-55kW or more and 400V-90kW or more.
*2: External braking resistor (option)
*3: To supply a DC power, connect the cables to the PA/+ and PA/- terminals.
*4: If you want to use a DC power supply to operate the inverter (200V: 18.5kW or more, 400V: 22kW or more), be
sure to contact your supplier customer support center, because an inrush current limiting circuit is required in such
a case.
*5: Refer to Section 2.3.2 for chip switch functions.
*6: The functions assigned to terminals OUT1, VI/VII and RR/S4 can be switched by changing parameter settings. For
details refer to Section 2.3.2.
*7: To supply control power from an external power supply for backing up the control power supplied from the inverter,
an optional control power backup device (CSP003Z) is required. In such a case, the backup device is used at the
same time with the internal power supply of the inverter.
