10.6Connection 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 power	Applicable motor (kW)	Inverter type
Single phase	0.4	VFAS1-2007PL
200~240V	0.75	VFAS1-2015PL
50/60Hz	1.5	VFAS1-2022PL
	2.2	VFAS1-2037PL
	3.7	VFAS1-2055PL
	5.5	VFAS1-2075PL

Note: Set the parameter ￿￿￿￿ to ￿ (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.
