Motor Wiring Overview - Danfoss VLT HVAC Operating Instructions Manual

4. Electrical installation
All types of three-phase asynchronous stand-
ard motors can be connected to the frequency
converter. Normally, small motors are star-
connected (230/400 V, D/Y). Large motors are
delta-connected (400/690 V, D/Y). Refer to
the motor name plate for correct connection
mode and voltage.

NB!
In motors without phase insulation paper or other insulation reinforcement suitable
for operation with voltage supply (such as a frequency converter), fit an Sine-wave
filter on the output of the frequency converter. (Motors that comply with IEC
60034-17 do not require an Sine-wave filter).
