Figure 15 on page 31 shows the grounding point location on the router.
A protective earthing terminal bracket is required for connecting the chassis to earth
ground. This two-holed bracket attaches on the side of the chassis through the mounting
rail and provides a protective earthing terminal for the router. The grounding points are
studs sized for 10–32 screws. The 10–32 screws are provided with the MX204 router. The
grounding points are spaced at 0.75-in. (19.1-mm) centers.
Two threaded holes are provided on the rear left side of the chassis for connecting the
router to earth ground. The grounding points fit 10–32 screws.
NOTE: Additional grounding is provided to an AC-powered router when you
plug its power supply modules into grounded AC power receptacles.

You must provide one grounding cable lug that attaches to the grounding cable and
10–32 screws used to secure the grounding cable to the grounding points.
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.
The grounding lug required is a Panduit LCD10-10A-L or equivalent (not provided). The
grounding lug accommodates 12 AWG (2.5 mm²) stranded wire. The grounding cable
that you provide for the chassis must be the same size or heavier than the input wire of
each power supply module. Minimum recommendations are 12 AWG (2.5 mm²) stranded
wire, 60° C wire, or as permitted by local code.
