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 26 AH 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.
