[Standard connection diagram - sink logic]
The figure below shows an example of typical wiring in the main circuit VFAS1-6400KPC to 6630KPC inverter.
Main circuit power source
500/575V class : 315(500HP)~500kW(700HP)
690V class :
Three-phase 500~690V-50/60Hz

*1: AC reactor (PFL): Mandatory for VFAS1-6110KPC and above.
*2: Transformer for fan supply (TRS) ⇒Refer to section 1.4.4.
*3: ⇒ Refer to Section 2.3.2 for switch functions.
*4: 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.
*5: 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.
*6: For PWR connection conforming to safety standards, refer to Section 9.3.
*7: If you use a braking unit (optional) and external braking resister (optional) in combination.
*8: TRS(Transformer for fan power supply) can not be used this system for VFAS1-6110KPC and above.
