Cable to Enclosure Shielding
Shielded motor, feedback, serial communications and external encoder cables were used for compliance testing and
are necessary to meet the EMC requirements. Each cable shield was grounded at the enclosure wall by the type of
grommet described earlier and shown in the following figure.

Cable Jacket
After tightening lock nut and positioning cable
so that Spring Contacts are contacting the
cable shield, tighten Cable Seal Housing.
Remove 1/2 to 1 inch of cable jacket.
The Spring Contacts will make a continuous
electrical path from the shield of the cable to
equipment ground.
When Lock Nut is tightened to inside of
enclosure, lock nut will cut through varnished,
anodized, and powder coated finishes.
Tighten lock nut so it cuts through the
finish and into housing.
