The power supply is installed along the rear panel.
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 that you supply.
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
connecting earth ground, see
Switch" on page
NOTE: Grounding is required for DC systems and recommended for AC
systems. An AC-powered switch gets additional grounding when you plug
the power supply in the switch into a grounded AC power outlet by using the
AC power cord appropriate for your geographical location.
