In addition, a backboard is needed to mount the system on the wall. One can be
made locally from 3/4 inch (1.9-cm) plywood. The dimensions depend on the
number of carriers, as shown in
weight plastic backboard may be ordered (COMCODE 847007523). In some
areas, fire or electrical codes require a flame-retardant backboard. Check with the
appropriate authorities to ensure that the proper material is provided. A template,
which shows the layout for mounting equipment, is available (COMCODE
847009206). It comes with safety, electrical, environmental, and space
requirements for the communications system.
CAUTION:
The AC outlet for the control unit should not be switch-controlled.
Plugging the control unit into an outlet that can be turned on and off
by a switch can cause accidental disconnection of the system.
The AC outlet must be properly grounded by using an AC receptacle
for a 3-prong plug.
Do not install the control unit outdoors.
Do not place the control unit near extreme heat (furnaces, heaters,
attics, or direct sunlight).
Do not expose the control unit to devices that generate electrical
interference (such as arc welders or motors).
Do not expose the control unit to moisture, corrosive gases, dust,
chemicals, spray paint, or similar material.
Do not place anything on top of the carriers.
Do not install the control unit under any device that may drip fluid,
such as an air conditioner.
