3.1.6 Mounting
The box frame housing is self-supporting, but designed to be bolted to the floor of the housing structure. The figure below shows the footprint of the box frame and the mounting points with dimensions (shown in inches). Consult the system design specifications to see if it is necessary to electrically isolate the frame from the floor structure. This is required in many installations. Insulator kit, part number AAB-0597 is available if required.
