3.1 Removal of Cover
To open the CD-1300-ST series use a coin in the slot on the bottom to release the snap. Lift the cover up slightly to disengage
the closure and remove cover with a downward motion to clear the catch at the top of the unit. The locations of controls and
terminals on the main circuit board are shown in the Figure 2.
3.2 Mounting
The CD-1300-ST series is designed for flush mounting with two fasteners. The locations of the mounting points (shown in
Figure 1) allow direct mounting on a standard simplex (single circuit) junction box. There is a wiring cutout in the center of the
unit near the terminal strips.
3.3 Wiring
This section describes the external connections to the CD-1300-ST Series. Wiring enters the chassis through the cutout in the
center of the unit.
