To ground the switch to earth ground, follow these steps. Make sure to follow any

grounding requirements at your site.

Step 1 Locate and remove the ground lug and the two number-10-32 ground-lug screws

from the rear panel of the switch. (See Figure C-3 for location.) Use a standard

Phillips screwdriver or a ratcheting torque screwdriver with a Phillips head. Set

the screws and the ground lug aside.

Step 2 If your ground wire is insulated, use a wire stripping tool to strip the 6-gauge

ground wire to 0.5 inch (12.7 mm) ± 0.02 inch (0.5 mm), as shown in Figure C-1.

Step 3

Slide the open end of the ground lug over the exposed area of the 6-gauge wire.

Step 4 Using a Panduit crimping tool, crimp the ground lug to the 6-gauge wire, as shown

in Figure C-2.
