3.3 Motor Connection
3.3.1 How to Connect the Motor
See the chapter Specifications for correct dimensioning of motor cable cross-section and length.
•
Use a shielded/armored motor cable to comply with EMC emission specifications, and connect this cable to both the decoupling plate and the motor
metal.
•
Keep motor cable as short as possible to reduce the noise level and leakage currents.
All types of three-phased asynchronous standard motors can be connected
to the frequency converter. Normally, small motors are star-connected
(230/400 V,
Δ/Y). Large motors are delta-connected (400/690 V, Δ/Y). Refer to
motor nameplate for correct connection and voltage.
Illustration 3.3: Star and delta connections.
Step 1: First, mount the earth cable.
Step 2: Connect wires to terminals either in star or delta-connection. See mo-
tor nameplate for further information.
Illustration 3.4: Mounting of earth cable and motor wires.
