To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, the router must be adequately grounded before power is connected.
To ground AC-powered or DC-powered routers, you must connect a grounding cable to
earth ground and then attach it to the chassis grounding points using the two screws
provided. (see Figure 56 on page

Figure 69: Connecting Chassis Grounding Points on the MX2020 Router

CAUTION: Before router installation begins, a licensed electrician must attach
a cable lug to the grounding and power cables that you supply. A cable with
an incorrectly attached lug can damage the router.
To ground AC-powered or DC-powered routers, connect a grounding cable to earth
ground and then attach it to the chassis grounding points using two screws. The top pair
of grounding points fits UNC 1/4–20 screws (American), and the lower pair fits M6 screws
(European). The grounding points are spaced at 0.625-in. (15.86-mm) centers. The cable
lugs get attached to the grounding cable, and the two UNC 1/4–20 screws are used to
secure the grounding cable to the top pair of grounding points.
WARNING: The router is a pluggable type A equipment installed in a restricted
access location. It has a separate protective earthing terminal (Metric [–M6]
and English [–¼-20] screw ground lugs) provided on the chassis in addition
to the grounding pin of the power supply cord. This separate protective earth
terminal must be permanently connected to earth.
