Before attaching wires to the surge protectors, route the cable into the shelter 
by passing the cable up through one of the strain reliefs at the bottom of the 
shelter. Consult the Surge Protector manual for instructions on attaching wires 
to the surge protectors. If using shielded cable, connect drain wires to each

After attaching all wires, tighten the compression nuts on the strain reliefs to 
secure the wires and create a weather-resistant seal. If there is a large air space 
around the wires, fill the space by wrapping the wires in electrical tape and/or 
sealing with silicone caulking.
