2. Screw the two (2) 3/8-in. NPT fittings into the foot of the housing.
3. Pull the cabling through the fittings into the housing. Tighten the fitting to 4.0 N m to
4.5 N m (35 in.-lb to 40 in.-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. Ensure that the holes in the rear cap are covered with the rubber plugs provided. Push in
until flush and then release.

Table 5.1: Recommended maximum cable lengths for housings equipped with 24 volt cameras, heaters, and
blowers
Wire sizes larger than 2.5 mm² (14 AWG) require a splice to accommodate the terminal block.

If using the feed-through option, ignore this step. Install one of the large ½-in. NPT
fittings into one of the holes in the rear cap.
2. Route the power cable through the fitting in the rear cap or through one of the feed-
through fittings in the foot.
