SUMMARY STEPS
1.
If your ground wire is insulated, use a wire-stripping tool to strip the ground wire to 0.5 inch ± 0.02 inch
(12.7 mm ±0.5 mm) (See the figure below).
2.
Slide the open end of your 2-hole ground lug over the exposed area of the ground wire.
3.
Using a crimping tool (as specified by the ground lug manufacturer), crimp the ground lug to the ground
wire as shown in the figure below.
4.
Use a Phillips head screwdriver to attach the 2-hole ground lug and wire assembly to the router with the
2 pan-head Phillips head screws.
5.
Connect the other end of the ground wire to a suitable grounding point at your site.
