[Standard connection diagram - sink logic]
The figure below shows an example of typical wiring in the main circuit 400V 500-630kW inverter.

*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: Three-phase power input is necessary to drive the fan if you want to use a DC power supply.
*5: Use a braking unit (optional) and an external braking resistor (optional) in combination.
*6: ⇒ Refer to Section 2.3.2 for switch functions.
*7: The functions assigned to terminals OUT1, VI/II and RR/S4 can be switched by changing parameter settings.
⇒ For details refer to Section 2.3.2.
*8: 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.
To back up control power, set the parameter  (Control power supply backup option failure monitoring) properly.
⇒ For more information, refer to 6.33.22.
*9: For PWR connection conforming to safety standards, refer to Section 9.3.
