VLT ® 2000 Series How to install your VLT I 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. I Survey of connection terminals All the terminals of a VLT frequency converter are shown below (3 x 380-460 V).
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. 42 MG.20.B6.02 – VLT is a registered Danfoss trademark
