Connecting Earth Ground to an EX Series Switch
To ensure proper operation and to meet safety and electromagnetic interference (EMI)
requirements, you must connect an EX Series switch to earth ground before you connect
power to the switch. You must use the protective earthing terminal on the switch chassis
to connect the switch to earth ground (see
).
NOTE:
A ground connection to the protective earthing terminal is not required
for an AC-powered switch. The AC power cords provide adequate grounding
when you connect the power supply in the switch to a grounded AC power
outlet by using the AC power cord appropriate for your geographical location.
WARNING:
The switch is installed in a restricted-access location.
CAUTION:
If external ground connection is required, ensure that a licensed
electrician has attached an appropriate grounding lug to the grounding cable
that you supply. Using a grounding cable with an incorrectly attached lug can
damage the switch.
