2.4.1 Cable Shield Grounding
Except for the power cord, all cables routed through the cord grips must be shield grounded against the enclosure.
• Use hardware provided in the parts kit to install shielding clamps on the grounding bracket at the bottom of the enclosure
• Install only the necessary amount of shielding clamps for the cord grips to be used
• Remove the insulated jackets and shielding per the following instructions
Shielding Procedure
1. Install the shielding clamps on the grounding rail using the clamp screws. Finger tighten the screws at this time.
2. Route the cables through the cord grips and the shielding clamps to determine the cable lengths required to reach the
appropriate cable connectors.
3. Mark cables to remove the insulated jacket as described below for Foil Shielded Cables and Braid Shielded Cables .
Foil Shielded Cables
Figure 2-6. Foil Shielded Cable
1. Strip the insulated jacket and foil 1/2'' (15 mm) past the shielding clamp.
2. Strip another 1/2'' of the insulated jacket, leaving the foil shielding exposed.
3. Fold the foil shielding back on the cable where the cable passes through the clamp.
4. Ensure the silver (conductive) side of the foil is turned outward.
5. Wrap the shield wire around the cable, ensuring it contacts the foil where the cable passes through the clamp.
6. Torque the shielding clamp screw to 10 in-lb (1.1 N-m), ensuring the clamp is around the cable and contacting the
shield wire.
Braid Shielded Cables
Figure 2-7. Braid Shielded Cable
1. Strip the insulated jacket and braided shielding from a point just past the shielding clamp.
2. Strip another 1/2'' (15 mm) of the insulated jacket, leaving the braid exposed where the cable passes through the clamp.
3. Torque the shielding clamp screw to 10 in-lb (1.1 N-m), ensuring the clamp is contacting the braided shielding of the
cable.
