Location of Ground Screw
The ground screw is located on the left side of the chassis and is accessible from the

Insert the stripped end of the grounding wire into the open end of the lug.
3.
Use a ring lug crimping tool (do not use pliers) to secure the grounding wire in place
in the lug.

bottom side of the lug) to attach the lug to a grounding position on the chassis. Tighten
to 20 in-lb.
5.
Prepare the other end of the grounding wire with a lug, and connect it to the equipment
frame with the screw and two lock washers (one on the top side and one on the
bottom side of the lug) supplied in the installation kit.
