Connecting the Grounding Cable to the M120 Router
You ground the router by connecting a grounding cable to earth ground and then attaching
it to the chassis grounding points using two screws. You must provide the grounding
cables (the cable lugs are supplied with the router).
1. Connect the grounding cable to a proper earth ground.
2. Verify that a licensed electrician has attached the cable lug provided with the router
to the grounding cable.
3. Make sure that grounding surfaces are clean and brought to a bright finish before
grounding connections are made.
4. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
5. Place the grounding cable lug over the grounding points. The left pair is sized for M6
screws, and the right pair is sized for UNC 1/4-20 screws.
6. Secure the grounding cable lug to the grounding points, first with the washers, then
with the screws.
7. Verify that the grounding cabling is correct, that the grounding cable does not touch
or block access to router components, and that it does not drape where people could
trip on it.
