[Standard connection diagram - sink logic]

The figure below shows an example of typical wiring in the main circuit 400V 355-500kW inverter.

*10:Be sure to short across NO-CC

*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: When RES-CC is shorted and then opened, the inverter protective status is reset.
