System Overview
System Cabinets
2.3 System Cabinets
The control panel and modules are installed in a CAB-4 series backbox. There are four different
sizes available, holding from one to four rows of equipment plus batteries (up to two 25AH
batteries). Backboxes are ordered separately from doors. The doors can be mounted on the left or
the right side of the cabinet; reversible hinges are provided so that this choice can be made in the
field. Doors open a full 180 degrees and have locks. Mounting methods include surface-mounting
or semi-flush mounting on a wall between 16 inch (40.64 cm) on-center studs. A trim ring option is
available for semi-flush mounting.
External measurements for each backbox are provided below; door dimensions are larger. Refer to
CAB-3/CAB-4 Series Cabinet Installation Document
(shipped with the cabinet) for specific
mounting drawings and door dimensions.
The control panel and adjacent first-row modules mount in chassis CHS-M2, typically in the
first/top row of the backbox. Additional rows of modules can be mounted in chassis CHS-4N
and/or CHS-4L.
Some additional components available in the CAB-4 series include:
DP-DISP
An Inner Dress Panel for covering the backbox area surrounding display panels and
various modules (required for Canadian installations).
BMP-1
Blank Module Plate for covering an unused dress-panel position. Provides another option
for mounting modules such as TM-4, NCM-W, or NCM-F.
