Chapter 3 Power Supply and Fan Module Installation
Installing a DC-Power Supply
Grounding the Switch
To make sure that the equipment is reliably connected to earth ground, follow the grounding procedure
instructions 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
Follow any grounding requirements at your site.
Step 1 Locate the ground lug screw and the lug ring in the switch accessory kit. For a dual-ground connection,
locate the dual-ground adaptor and dual-hole lug that ships with the DC-power-supply module.
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 3-3 ). Use 12-gauge copper ground wire for the
single-ground connection. Use 6-gauge copper ground wire for the dual-ground connection.
Figure 3-3 Stripping the Ground Wire
Step 3
Slide the open end of the ground lug over the exposed area of the wire.
Step 4 Using a Panduit crimping tool, crimp the ground lug to the wire ( Figure 3-4 ).
Figure 3-4 Crimping the Ground Lug
Step 5 Use the ground screw to attach the single-ground lug and the wire assembly or the dual-ground adaptor
to the switch rear panel. For a dual-ground adaptor, attach the dual-hole lug and the wire assembly to the
adaptor with the supplied nuts (
Figure 3-5 ).
