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.
