Confirming the Location of the Control Unit	Page 1-3

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 under any device that may drip fluid, such as an air conditioner.

In addition, a backboard is needed to mount the system on the wall. One can be made locally from 0.75-in. (1.9-cm) plywood. The dimensions depend on the number of carriers, as shown in Table 1–2. A newly designed pre-drilled, light-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 is available (COMCODE 847009206). It shows the layout for mounting equipment. It also comes with safety, electrical, environmental, and space requirements for the communications system.

Table 1–2. Control Unit Space Requirements

Carrier	Requirements
Basic carrier	14" w by 23" h by 12" d
	(35.6 cm by 58.4 cm by 30.5 cm)
Basic carrier + 1 expansion carrier	25" w by 23" h by 12" d
	(63.5 cm by 58.4 cm by 30.5 cm)
Basic carrier + 2 expansion carriers	37" w by 23" h by 12" d
	(94 cm by 58.4 cm by 30.5 cm)
Backboard
Without Systimax	6’ w by 3’ h by 0.75" d
	(182.9 cm by 91.4 cm by 1.9 cm)
With Systimax	7’ w by 4’ h by 0.75" d
	(213.4 cm by 121.9 cm by 1.9 cm)

It is important that the location selected for the control unit meets all of these specifications and that the backboard is in place before installation. If the location has already been selected and changes are needed, arrange for these changes before installation.
