Step 3: Connect the Grounding Cable
You ground the router by connecting a grounding cable to earth ground and then attaching
it to the chassis grounding points using two SAE 10-32 screws. You must provide the
grounding cables (the cable lugs are supplied with the router). To ground the MX5, MX10,
MX40, or MX80 router:
1. Verify that a licensed electrician has attached the cable lug provided with the router
to the grounding cable.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to an approved site ESD grounding point. See the instructions for your site.
3. Ensure that all grounding surfaces are clean and brought to a bright finish before
grounding connections are made.
4. Connect the grounding cable to a proper earth ground.
5. Detach the ESD grounding strap from the site ESD grounding point.
6. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
7. Place the grounding cable lug over the grounding points on the upper rear of the
chassis (see Figure 7 on page 10).
8. Secure the grounding cable lug with the screws. The holes are sized for SAE 10-32
screws.
9. Dress the grounding cable and verify that it does not touch or block access to router
components, and that it does not drape where people could trip on it.
