J-EX8200 switch, connect a grounding cable to earth ground and then attach it to the
chassis grounding points.
CAUTION: For installations that require a separate grounding conductor to
the chassis, use the protective earthing terminal on the J-EX8200 switch
chassis to connect to earth ground. Before switch installation begins, a
licensed electrician must attach a cable lug to the grounding cables that you
supply. See “Connecting Earth Ground to a J-EX Series Switch” on page 129.
A cable with an incorrectly attached lug can damage the switch.
A pair of threaded inserts (PEM nuts) is provided on the right side towards the top rear
corner of the J-EX8208 chassis for connecting the switch to earth ground. The grounding
points fit UNC ¼-20 screws. The grounding points are spaced at 0.625 in. (15.86 mm).
NOTE: Grounding is provided to an AC-powered switch when you plug its
power supplies into grounded AC power receptacles.
Figure 26 on page 54 shows the cable lug that attaches to the grounding cable in a
J-EX8208 switch.
Figure 26: Grounding Cable Lug For a J-EX8208 Switch
The grounding cable that you provide for a J-EX8208 switch must be 6 AWG (13.3 mm
2
),
minimum 60°C wire, or as permitted by the local code.
WARNING: The switch is pluggable type A equipment installed in a
restricted-access location. It has a separate protective earthing terminal
provided on the chassis in addition to the grounding pin of the power supply
cord. This separate protective earthing terminal must be permanently
connected to earth ground for installations that require a separate grounding
conductor to the chassis.
