Step 3: Connect the Grounding Cable

10
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, the router must be adequately grounded before power is connected.
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
in the form of studs sized for M5 Pan Head screws. The M5 Pan Head screws with
integrated washers are provided in the accessory kit. The grounding points are spaced
at 0.75-in. (19.1-mm) centers.
You ground the router by connecting a grounding cable to earth ground and then attaching
it to the chassis grounding points by using two M5 Pan Head screws. You must provide
the grounding cables (the cable lugs are supplied with the router).
NOTE: The grounding lug required is a Panduit LCD10-10A-L or equivalent
(not provided). The grounding lug accommodates 14–10 AWG (2–5.3 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. Minimum
recommendations are 14–10 AWG (2–5.3 mm²) stranded wire, 60° C wire,
or as permitted by local code.
To ground the MX204 router:
Verify that a licensed electrician has attached the cable lug provided with the router
1.
to the grounding cable.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
2.
the other end of the strap to an approved site ESD grounding point. See the instructions
for your site.
Ensure that all grounding surfaces are clean and brought to a bright finish before
3.
grounding connections are made.
Connect the grounding cable to a proper earth ground.
4.
Detach the ESD grounding strap from the site ESD grounding point.
5.
Connect the grounding strap to one of the ESD points on the chassis.
6.
Figure 4 on page 4 shows the ESD point on the router.
Place the grounding cable lug over the grounding point on the side of the chassis (see
7.
Figure 12 on page 11).
