You may mount the shelter against a wall or other vertical surface or you may
simply lay it down on a horizontal surface. The preferred mounting method is
to mount it on a vertical surface in a protected location with the rubber grommet facing down.
Note: You may install the wires through the grommet and into the terminal blocks before or after mounting
1. Hold the shelter against the mounting surface and mark the location of the screw holes.
Use a pencil or a center punch to mark the location of the screw holes.
2. Drill pilot holes in the marked locations using a drill with a #29 (.136”, 3.5 mm) drill bit.
3. Secure the shelter to the mounting surface using the #8 x Ω ” (19 mm) screws as

1. Route the ground wire through the grommet at the base of the shelter and attach to a
suitable ground, such as Davis’s Grounding Kit (#7780).
2. Prepare the cables by cutting the modular connector off (if using standard cable),
stripping 1” (25 mm) of the jacket (the outer covering) and the shield (the foil-like
inner covering on shielded cables) from each cable, and stripping ∫ ” (12.5 mm) of
insulation (the colored covering) from each individual wire.
3. Loosen both hex nuts on each post of the Surge Protector.
Loosen the top hex nut as far as possible; loosen the bottom hex nut about
half way along the screw post.
4. Pass the cables through the grommet in the base of the shelter.
5. Place one wire from the first cable between the two bottom washers.
Bend the wire around the screw post.
6. Tighten the bottom hex nut until the wire is secured.
7. Place the same colored wire from the second cable between the two top washers.
Bend the wire around the screw post.
8. Tighten the top hex nut until the wire is secured.

9. Repeat this procedure for each colored wire.
10.If attaching shielded cable, loosen the top hex nut on the mounting post (where the
Surge Protectors are held in place) and place the bare drain wires from each cable
between the two flat washers, bending the wires around the screw post.
The drain wires go in the same location as the ground wire (see “Attaching
Surge Protectors” on page 3).
11. Tighten the top hex nut on the mounting post until the drain wires are secured.
