CHAPTER 10
Connecting the Switch
Connecting Earth Ground to a J-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 J-EX Series switch chassis to connect to the earth
ground (see Figure 57 on page 129).
Figure 57: Connecting a Grounding Cable to a J-EX Series Switch
Before you connect earth ground to the protective earthing terminal of a J-EX Series
switch, ensure that a licensed electrician has attached an appropriate grounding lug to
the grounding cable.
