Dimensions
Figure 2. Case Dimensions
Prior to mounting the Series CN8200 in your panel, make
sure that the cutout opening is of the right size, 1.771" x
1.771" (45 mm x 45 mm), and deburred to enable a smooth
fit. A minimum of 4" (100 mm) of depth behind the panel is
required.

Wiring
IMPORTANT: All electrical wiring connections should be made
only by trained personnel, and in strict accordance with the
National Electrical Code and local regulations.
The Series CN8200 controller has built-in circuitry to reduce
the effects of electrical noise (RFI) from various sources.
However, power and signal wires should always be kept
separate. We recommend separating connecting wires into
bundles: power; signal; alarms; and outputs. These bundles
should then be routed through individual conduits. Shielded
sensor cables should always be terminated at one end only.
If additional RFI attenuation is required, noise suppression
devices such as an R.C. snubber at the external noise source
may be used.
