This equipment is intended to be grounded. Ensure that the host is connected to
earth ground during normal use.
When installing the unit, always make the ground connection first and
disconnect it last.
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.
Locate the ground lug and the two number-10-32 screws from the switch rear
panel. 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 millimeter [mm]) ± 0.02 inch (0.5 mm) as shown in
Figure 2-21.
