Grounding the Switch
Follow the grounding procedures at your site and observe these warnings:
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
Follow the grounding procedure instructions, and use a UL-listed lug (included with the switch) for
number-6 AWG wire and 10-32 ground-lug screws.
Note
You can use the grounding lug to attach a wrist strap for ESD protection during servicing.
Follow these steps to install a dual-hole lug on the switch. Be sure to follow any grounding requirements
at your site.
Step 1
Use a Phillips screwdriver or a ratcheting torque screwdriver with a Phillips head to remove the ground
screw from the cable side of the switch. You need the screw in Step 4.
Step 2
Strip the 6-gauge ground wire to 0.5 inch (12.7 mm) ± 0.02 inch (0.5 mm). See
Figure 3-3
. Stripping
more than the recommended amount of wire can leave exposed wire from the connector.
