Danfoss VLT AQUA Drive - Motor Wiring Overview

All types of three-phase asynchronous standard 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.
Illustration 5.12: Terminals for motor connection
NB!
In motors without phase insulation paper or other insulation reinforcement suitable for operation with voltage supply (such as a fre-
quency converter), fit a sine-wave filter on the output of the frequency converter. (Motors that comply with IEC 60034-17 do not require
an Sine-wave filter).
