Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024 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. To ground the switch to earth ground, follow these steps. Make sure to follow any grounding requirements at your site. Step 1 Step 2 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. 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.

Grounding the Switch
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable grounding is available.
Statement 1024
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.
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
.
