CAUTION:
The AC outlet for the control unit cannot be switch-controlled.

disconnection of the system.
Hardware Preassembly Process
If an installation is to be preassembled, wired, programmed, and tested
on the new lightweight plastic backboard, see “Installing the Backboard.”
Backboard Requirements
The backboard should be wide enough to accommodate the carrier and
up to two additional carriers, assuming that system growth is
anticipated. There should be enough room on each side of the control
unit for the necessary wiring fields.
