Pull the cabling through the fittings into the housing.
Tighten the fitting to 4.0 Nm to 4.5 Nm (35 inch-lb to
40 inch-lb). This torque rating is approximately 1 to 1.5
turns past the point where the fitting starts to grip the
wire. Failure to do this will result in water damage to all
electronic parts.
4.
Attach the foot to the top bracket of the mount.
5.
Be sure that the holes in the rear cap are covered with the
rubber plugs provided. Push in until flush and then release.

Standard SJ cord (or better) acceptable for outdoor use.
Installation must conform to NEC 400-4 CEC rule 4-010 and be
marked with OUTDOOR, W, or W-A. For 24-volt cameras, use
the recommended maximum cable lengths chart for selecting
the proper wire size.

Route the power cable through the fitting in the rear cap or
one of the feed-through fittings in the foot.
The terminal block accepts wire ranging from 0.5 mm

(20 AWG to 14 AWG). When using larger wire sizes,
splice to a smaller size wire at the terminal block end. The
splice may need to be enclosed in a junction box if it does not
pass through the fittings.
