Specification

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.

Outside Enclosure

O-Ring seals against outside of enclosure to meet IP68 (comparable to NEMA 6)

Spring Contacts

Cable Shielding

Cable Jacket

Inside Enclosure

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.

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.

After tightening lock nut and positioning cable so that Spring Contacts are contacting the cable shield, tighten Cable Seal Housing.
