[Standard connection diagram - sink logic]
The figure below shows an example of typical wiring in the main circuit 400V 355-500kW 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 Toshiba distributor, 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 6.33.24.
*9: For PWR connection conforming to safety standards, refer to Section 9.3.
*10: When RES-CC is shorted and then opened, the inverter protective status is canceled.
