The figure below shows an example of typical wiring in the main circuit of a 200V 0.4-45kW/400V 0.75-75kW inverter.
Main circuit power source
200V class:
0.4~45kW Three-phase
200~240V-50/60Hz
400V class:
0.75~75kW Three-phase
380~480V-50/60Hz

*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).
*2: The DC reactor is built in for models 200V-11kW~45kW and 400V-18.5kW~75kW.
*3: The noise filter is built in for models 200V-45kW or smaller and all of 400V.
*4: External braking resistor (option). Dynamic braking drive circuit built-in (GTR7) as standard for models 160kW or smaller.
*5: To supply a DC power, connect the cables to the PA/+ and PC/- terminals.
*6: 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.
*7: Refer to Section 2.3.2 for chip switch functions.
*8: 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.
*9: 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 (CPS002Z) is required. In such a case, the backup device is used at the same time
with the internal power supply of the inverter.
*10: The optional control power backup unit can be used with both 200V and 400V models.
