WARNING:
DC-powered switches are intended for installation only in a
restricted-access location.
Before you begin connecting DC power to the switch, ensure that you have connected
earth ground to the switch chassis.
CAUTION:
Before you connect power to the switch, a licensed electrician
must attach a cable lug to the grounding and power cables. A cable with an
incorrectly attached lug can damage the switch (for example, by causing a
short circuit).
To meet safety and electromagnetic interference (EMI) requirements and
to ensure proper operation, you must connect the switch 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 switch chassis to connect to the earth ground. For instructions on
