5.6 Camera/Lens Installation
Place the camera/lens combination onto the rail
assembly.
Fixed Lens Cameras
: Position the camera/lens so that
the lens is positioned over the heater but not past it.
Secure the camera to the rail assembly with the
1/4-20 x 3/8in. BHC screw, a nylon bushing, and a
0.4mm (0.016in.) plastic spacer. Place the nylon bushing
over the screw and slide both between the rails through
the front cut-out section. Slide the spacer over the screw
so it is positioned in-between the rails and the camera.
See FIGURE 5.
FIGURE 5 Mounting a Fixed Lens Camera
Zoom Lens Cameras
: Position the camera/lens so that
the lens is positioned over the heater but not past it. The
camera/lens combination will determine the screws and
spacers that will be needed. Secure the camera and lens
to the rail assembly with 1/4-20 BHC screws, nylon
bushings, and plastic spacers. Place the nylon bushings
over the screws and slide both between the rails through
the front cut-out section. Slide the spacer over the screw
so it is positioned in-between the rails and the camera.
There are four large spacers (3.2mm) and four small
spacers (0.4mm) provided. See FIGURE 6.

Camera/Lens Wiring
WARNING: Only use the cables specified under
INSTALLATION, Cable Requirements
for wiring of all
cameras and lenses.
5.7.1
Liquid-Tight Fittings
The dual-male threaded portion of the two 1/2in. NPT
and one 3/8in. NPT liquid-tight fittings are preinstalled
in the rear of the base assembly. If possible, do not
remove or loosen these parts. They have been installed
to a specified torque to prevent water damage. The small
3/8in. NPT fitting will accept cables with diameters from
4.6mm (0.181in.) to 7.9mm (0.31in.). The two large
1/2in. NPT fittings will accept cables with diameters
from 4.3mm (0.170in.) to 11.9mm (0.470in.). See
FIGURE 7.
Be sure to securely tighten all fittings to ensure a
liquid-tight seal. Not doing so could damage the
camera, the housing, or both.
If a sealant will be used, be sure it is a neutral
cure type. Sealants that release acetic acid may
harm camera electronics.
If it is necessary to use PG type conduit, a HS9385NPT
kit is available. The HS9385NPT kit contains a wire grip
with two PG11 and one PG7 tapped holes. The NPT
wire grip is removed and replaced with the PG version.

Plug Insertion
If no lens control or feed-through wiring will be used,
install the 3/8in. NPT plug provided. Remove the liquid-
tight fitting and insert the plug in the small bottom
center 3/8in. NPT hole. Use a 8mm or a 5/16in. hex
wrench to tighten securely. Failure to do so will result in
water damage to all electronic parts. See FIGURE 8.
