Mains and motor connection of VLT 3575-3600

HVAC and VLT 3542-3562 (230 V) HVAC

Motor connection

All types of three-phase asynchronous standard mo-

tors can be used together with VLT 3500 HVAC.

In general, smaller motors (220/380 V,

∆

/ Y) are star-

connected. Larger motors (380/660 V,

∆

Y) are delta-

connected.

The correct connection mode and voltage can be

seen from the nameplate on the motor.

■

Direction of rotation

The factory setting gives clockwise rotation when the

output on the VLT 3500 HVAC has been connected

as follows:

Terminal 96: connected to U

Terminal 97: connected to V

Terminal 98: connected to W

The direction of rotation can be changed by swapping

two phases of the motor cable.
