Grounding Cable Specicaons for an EX9200 Switch | 136
To ensure proper operaon and to meet safety and electromagnec interference (EMI) requirements,
you must connect an EX9200 switch to earth ground before you connect power to the switch. You must
use the protecve earthing terminal on the switch chassis to connect the switch to earth ground.
WARNING: The switch is installed in a restricted-access locaon. It has a separate
protecve earthing terminal on the chassis that must be permanently connected to
earth ground to adequately ground the chassis and protect the operator from electrical
hazards.
CAUTION: Before switch installaon begins, ensure that a licensed electrician has
aached an appropriate grounding lug to the grounding cable that you supply. Using a
grounding cable with an incorrectly aached lug can damage the switch.
Grounding Points Specicaons for an EX9200 Switch
To meet safety and electromagnec interference (EMI) requirements and to ensure proper operaon, the
switch must be adequately grounded before power is connected. To ground AC-powered and DC-
powered switches, you must connect a grounding cable to earth ground and then aach it to the chassis
grounding points using the two screws provided.
Two threaded inserts (PEM nuts) are provided on the upper rear of the chassis for connecng the switch
to earth ground. The grounding points t UNC 1/4–20 screws (American). The grounding points are
spaced at 0.625 in. (15.86 mm) centers.
NOTE: Addional grounding is provided to an AC-powered switch when you plug its power
supplies into grounded AC power receptacles.
