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
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last.
Statement 1046
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 a dual-hole ground lug on the switch. Make sure to follow any grounding
requirements at your site.
Step 1
Locate the dual-hole lug that ships with the switch. (The grounding lug is included in the packaging
accessories.)
Step 2
If your ground wire is insulated, use a wire stripping tool to strip the 6 AWG ground wire to 0.875 inch (12.7
mm) ± 0.02 inch (0.5 mm)
