10.6 Connection of a DC power supply and other electric units
Besides a three-phase commercial power supply, a single-phase 200V power supply (5.5kW or less) and a DC power
supply can be connected to the VFAS1 inverter.
When connecting each of these units, keep in mind the points described in the following sections.
10.6.1 Connection of a single-phase 200V power supply
The table below shows which model to select when operating a three-phase induction motor, using a single-phase
200V power supply (200-240V, 50/60Hz).

(input phase failure detection mode selection: disabled).
10.6.2 When using the inverter along with a DC power supply
Keep the following in mind when connecting a DC power supply to the VFAS1 (PA/+ and PC/- terminals).
Note 1: An optional initial charger (MCR-2550) is needed for middle- and large-capacity models.
Note 2: 200V-75kW and 400V-110kW or more models are needed to change the connecting for the cooling fan.
Note 3: A DC reactor does not need to be connected to the inverter.
For details about use in combination with a DC power supply, refer to the instruction manual (E6581432) specified
in section 6.42.
