Step 1 Strip one end of the ground wire to expose approximately 3/4 inch (20 mm) of conductor.
Step 2 Crimp the 14 AWG green ground wire to a UL Listed/CSA certified ring terminal, using a crimping tool that is
recommended by the ring terminal manufacturer. The ring terminal provided on the back panel of the router is suitable
for a No. 6 grounding screw.
Step 3 Attach the ring terminal to the chassis as shown in Figure 1. Use a number 2 Phillips screwdriver and the screw supplied
with the ring terminal. Tighten the screw to a torque of 8 to 10 inch-pounds (0.9 to 1.1 newton meters.)
Step 4 Connect the other end of the ground wire to a known good electrical grounding point such as a service panel grounding lug.
Consult a licensed electrician if you have any questions about the suitability of the ground connection.
