- Where possible, lay the cable shields directly behind the cable entry into
the drive. In the case of signal and data cables, use the shield connection
points which are provided in the control cabinets or the shield connection
kit for the Control Unit.
- Avoid interruptions in cable shields caused by intermediate terminals or
service switches without a conductive metal housing.
- Fasten the cable shields both for power cables as well as for signal and
data cables using the appropriate EMC shield clamps (use the shield
connection kit supplied for the Control Unit) or EMC cable glands. The
shield clamps must connect the shield to the EMC shield bar or the shield
support element for control cables through a low inductive connection over
a large surface area.

Drives with IP55 degree of protection / UL Type 12 (Power Module PM230) can be
installed and operated in a closed control cabinet as well as without a control
cabinet.
Shielding of the drive to comply with EMC standards

- Use a shielded cable if terminal wiring is required for the Control Unit.
Guide this through the base plate and place the shield either on the shield
connection kit of the Control Unit or using the EMC cable gland.
- Expose the motor cable shield at the point where the cable is fed through
the base plate and ensure that it is in complete contact with an EMC cable
gland. It is important for the shield to be fed through the cable gland and
then to be connected at the designated place inside the enclosure once
again. This ensures that both the gland plate and the enclosure are in
contact with the shield.
- Feed the motor cable through the right-hand opening on the gland plate, in
particular in the case of Power Modules of frame size C and with filter class
B.
