Power input terminal
VFPS1-5022PM~5075PM:
Three-phase 500~600V-50/60Hz
Connect to a (3-phase induction) motor.
Connect a braking resistor.
Change the parameters
250kW models and larger are not equipped with terminal PB.
This is a negative potential terminal in the internal DC main circuit.
Shorted by a short bar when shipped from the factory (90kW or smaller).
VFPS1-6110KPC or larger
Inverter's cooling fan power input terminals. Don't need to connect if you use TRS.
(TRS: Transformer for fan supply)
