Follow these procedures to ground the router to earth ground. Ensure you follow any grounding
requirements at your site.
Step 1
Remove the grounding screw/nut (ground-lug screw) from the rear panel of the router (see
Figure 3-2 on
page 3-6
). Use a standard Phillips screwdriver or a ratcheting torque screwdriver with a Phillips head.
Step 2
Set the screw aside.
Step 3

± 0.02 inch (12.7 mm ±0.5 mm) for the ground lug or ring terminal (see
Figure 3-3
).
