System Cabinets

2.4 System Cabinets
The CPU 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 (406.4 mm) on-center studs. A trim ring option is
available for semi-flush mounting.
External measurements for each cabinet size are provided below. Refer to CAB-3/CAB-4 Series
Cabinet Installation Document (shipped with your cabinet) for specific mounting drawings and
dimensions.

compatible with CAB-4 series enclosures.
