Grounding the Chassis
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 During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the
backplane with your hand or any metal tool, or you could shock yourself. Statement 94
Warning This equipment needs to be grounded. Use a green and yellow 14 AWG ground wire to connect the host to earth
ground during normal use. Statement 190
To connect the chassis to a reliable earth ground, using a ring terminal and size 14 AWG (2 mm
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 3. 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.
