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 Figure 34 on page 104).
WARNING: The switch is installed in a restricted-access location. It has a
separateprotectiveearthing terminal on the chassis thatmust be permanently
connected to earth ground to adequately ground the chassis and protect the
operator from electrical hazards.
CAUTION: Beforeswitchinstallation begins, ensure that a licensedelectrician
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.
