All types of three-phase asynchronous standard
motors can be connected to the FC 300. 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 LC filter on the output of the FC 300.
