4.5 Installation of power supply, grounding and motor cable

Drive is to be connected with ground/PE by separate grounding wire.

1-phase power supply should be connected to L1/L, L2/N.

3-phase power supply should be connected to L1, L2 and L3.

Phase sequence of power supply is not important and cable doesn’t have to be a shielded.
400V 230V
690V 400V
STAR DELTA

Motor cable must be a shielded cable to fulfill EMC requirements. Example of cables to be
used are RKFK, Ölflex Classic 100 CY, FKKJ-EMC, or similar.

Shield of the motor cable should be connected to ground/earth in both ends. On motor side
an EMC-gland is to be used.

Shield of motor cable is to be connected to ground terminal in the drive itself. For IP20
drives the shield can instead be clamped to the mounting plate with a clip.

Motor must also be well attached into the mechanical frame of the machinery and have the
same potential as the electrical cabinet. Separate earth connection might be necessary.

Motor cable should avoid to be installed close to telephone-, network- or signal wiring.
Minimum distance is 30 cm.
