•
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.

•
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 be connected to the Protective earth terminal or clamped to the
mounting plate with a clip. For IP66 drives shield is to be connected to the Protective earth
terminal or by an EMC cable gland.
•
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 being installed close to telephone-, network- or signal wiring.
Minimum distance is 30 cm.
•
Protective grounding of motor is connected to drive
•
Motor cable should be connected to U, V, W.
