    Grounding the MX2020 Router

    To ground the router, you need the following tools:

    • Phillips (+) screwdriver, number 2
    • ESD grounding wrist strap
    • Two UNC 1/4–20 nuts and washers
    • Grounding lug, 4-AWG for 80-A input or 6-AWG for 60-A input
    • Grounding cable, minimum 10 AWG wire (not provided)

    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). To connect the grounding cable (see Figure 1):

    1. 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.
    2. Ensure that all grounding surfaces are clean and brought to a bright finish before you make grounding connections.
    3. Connect the grounding cable to a proper earth ground.
    4. Verify that a licensed electrician has attached the cable lug provided with the router to the grounding cable.
    5. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    6. Place the grounding cable lug over the grounding points on the rear of the chassis. The upper pair is sized for UNC 1/4-20 nuts, and the lower pair is sized for M6 nuts.
    7. Secure the grounding cable lug to the grounding points, first with the washers, then with the nuts.
    8. 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.
