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.

Ground Lugs
The metal enclosure includes one ground lug pre-mounted near the top and one spare ground lug, which
mounts on one of the available ground lug studs. You can also re-locate the pre-mounted ground lug to
minimize the length of shield used.
