1.4 Cable Clamp and Shielding
If the cables wired to the PCNC unit need to be shielded, they must be grounded using the
grounding plate with cable clamp hardware. Because this clamp serves both as cable support
and shielding, they must be installed carefully so that safe system motion can be assured.
1. Peel the cable coating to expose the cable where it connects the grounding plate with the
cable clamp.
2. The cable clamps (with the cables) must be installed to the grounding plate as shown in the
following diagram:
