Motor connection ≤ 10 HP [7.5 kW] IP 55
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 nameplate for correct
connection mode and voltage.
NOTE
In motors without phase insulation paper or other insulation reinforcement suitable for operation
with voltage supply (such as adjustable frequency drive, fit an LC filter on the output of the FC 300.
