2.8 Enclosure Installation
The standard enclosure for the MultiMux is a Hoffman 12x10 fiberglass/polyester NEMA 4 type. The
enclosure can be mounted to a wall or other surface by attaching the 4 supplied mounting tabs to the
bottom of the enclosure using the supplied screws.
The placement of the mounting holes is depicted in the illustration below.

2.9 Lightning Protection
If the MultiMux is equipped with the optional lightning protection components then care must be exercised
in the installation to maximize their effectiveness. Specifically, an effective earth ground must be attached
to the MultiMux terminal board.
If the MultiMux was ordered in an enclosure with the lightning protection components then there will be a
ground lug on the side of the enclosure as shown in the illustration above. Attach a large gauge copper
wire (6-12 AWG) from the lug to a suitable earth ground, either a copper stake driven into the earth or a
known electrical system earth ground.
Copper earth ground stakes and connecting wire are available from Canary Systems.
