Connecting Earth Ground to an EX Series Switch | 173
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 Figure 52 on page 174).
You must install the EX Series switch in a restricted–access location and ensure that the chassis is
always properly grounded. EX Series switches have a two–hole protective grounding terminal provided
on the chassis. See Table 58 on page 165
switches. Under all circumstances, use this grounding connection to ground the chassis. For AC-
powered systems, you must also use the grounding wire in the AC power cord along with the two-hole
grounding lug connection. This tested system meets or exceeds all applicable EMC regulatory
requirements with the two-hole protective grounding terminal.
Ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable you
supply. Using a grounding cable with an incorrectly attached lug can damage the switch.
