All types of three-phase asynchronous standard
motors can be used with a VLT 4000 VT unit.
Small-size motors are normally star-connected.
(220/380 V, /Y).
Large-size motors are delta-connected (380/660
V, /Y). The correct connection and voltage can
be read from the motor nameplate.
NOTE
In older motors without phase coil insulation, a
LC filter should be fitted to the VLT AFD output.
