Shield of the motor cable should be connected to ground/earth in both ends. On motor side an
EMC-gland is to be used.

For IP20 drives the shield of the motor cable can be clamped to the mounting plate with a clip
as on picture below.

For IP55 and IP66 drives use an EMC gland and by that get a 360 degrees grounding of the shield.
