The figure below shows an example of typical wiring in the main circuit of a 200V 55, 75kW/400V 90-500kW inverter.
Main circuit power source
200V class:
55kW, 75kW Three-phase 300~220V-50Hz
Three-phase 200~240V-60Hz
400V class:
90kW Three-phase 380~480V-50/60Hz
110kW~500kW Three-phase 380~440V-50Hz
Three-phase 380~480V-60Hz

*1: Be sure to connect the DC reactor.
*2: To supply a DC power, connect the cables to the PA/+ and PC/- terminals.
*3: If you want to use a DC power supply to operate the inverter, be sure to contact your supplier customer support center,
because an inrush current limiting circuit is required in such a case.
*4: The noise filter is built in for models all of 400V.
*5: For models 200V-75kW and 400V-110kW or larger, three-phase power input is necessary to drive the fan if you want to use
a DC power supply.
*6: Every 200V model of any capacity and every 400V model with a capacity of 160kW or less come with dynamic braking unit
drive circuits (GTR7) built into them as standard equipment, so if your inverter is among these models, connect an external
braking resistor (optional) alone.
*7: If you are using a 400V/200kW model or larger, use a braking unit (optional) and an external braking resistor (optional) in
combination.
*8: Refer to Section 2.3.2 for switch functions.
*9: 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.
*10: 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.
*11: The optional control power backup unit can be used with both 200V and 400V models.
