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).

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.
