Chapter 3 Installing and Removing AC- and DC-Power-Supply Modules

Power-Supply Module Installation

Caution To make sure that the equipment is reliably connected to earth ground, follow the grounding procedure instructions, and use a UL-listed lug suitable for number-6 AWG wire and two number-10-32 ground-lug screws.

Follow these steps to install either a single-ground lug or a dual-ground lug on the switch. Make sure to follow any grounding requirements at your site.

Step 1 Locate the ground adaptor and the dual-hole lug that ships with the switch.

Step 2 If your ground wire is insulated, use a wire stripping tool to strip the 12-gauge or 6-gauge ground wire to 0.5 inch (12.7 mm) ± 0.02 inch (0.5 mm) (Figure 3-10). Use 12-gauge copper ground wire for the single-ground connection. Use 6-gauge copper ground wire for the ground connection.

Step 3 Slide the open end of the ground lug over the exposed area of the wire.

Step 4 Use a Panduit crimping tool to crimp the ground lug to the wire (see Figure 3-11).

Step 5	Remove the ground screw from the switch rear panel.
Step 6	Attach the dual-hole lug and the wire assembly to the adaptor with the supplied nuts (Figure 3-12).
Step 7	Use a ratcheting torque screwdriver to torque the ground-lug screws to 60 in-lb.
Step 8	Connect the other end of the grounding wire to an appropriate grounding point at your site or to the rack.
