How to connect the VLT to the motor
With the VLT 2000 Series you can use all standard
three-phase asynchronous motors.
Small motors (230/400 V, ∆/Y) are delta-connected to
230 V and star-connected to 400 V. Large motors are
delta-connected (400/690 V, ∆/Y).
The motor is connected to the VLT frequency con-
verter by means of terminals at the bottom of the en-
closure (the module).
The rotation direction can be changed by
swapping the phase motor cables (terminals
97 and 98) or by using the “Fwd/Rev” key, see
also page 47.
How to install your VLT

The control signals are described overleaf.
Do
not remove the motor and mains terminals
when the unit is connected to the mains.
Ensure that the power supply has been switched
off before you remove the motor and mains terminals.
