Cautions
■ The AC outlet for 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 via 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).
■ Each auxiliary power unit requires 1 outlet.
■ Do not expose the control unit to moisture, corrosive
gases, dust, chemicals, spray paint, or similar materials.
■ Do not place anything on top of the carriers.
■ Do not install under any device that may drip fluid, such
as an air conditioner.
In addition, a 3/4-inch plywood backboard is needed to mount the system on
the wall. The dimensions depend on the number of carriers, as shown in
Table 1-2. 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.
Table 1-2 Control Unit Space Requirements

It is important that the location you select for the control unit meets all of these
specifications and that the backboard is in place before installation. If you’ve
already selected a location and changes are needed, arrange for these
changes as soon as possible before installation.
