Connecting Earth Ground to an EX Series Switch
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect the switches to earth ground before you connect
them to power.
For installations that require a separate grounding conductor to the chassis, use the
protective earthing terminal on the EX Series switch chassis to connect to the earth
ground (see Figure 52 on page 141).
Figure 52: Connecting a Grounding Cable to an EX Series Switch
Before you connect earth ground to the protective earthing terminal of an EX Series
switch, ensure that a licensed electrician has attached an appropriate grounding lug to
the grounding cable.
