Mounting the Metal Enclosure
The metal enclosure has four (4) pre-drilled holes for mounting to the wall. Connect the ground lug to a true
earth ground. When locating mounting areas, ensure the metal enclosure is not close to high voltage
equipment and the cable lengths are within their maximum allowable distances.
For knockout and mounting hole locations/dimensions, see the diagram on the next page.
