Camera/Lens Installation
With the cradle removed from the housing, place the
camera/lens combination into the cradle assembly.
1. Fixed Lens Cameras: Position the camera/lens
1mm (0.04in.) away from the faceplate. The
camera/lens is secured to the cradle with a
1⁄4-20 button head cap screw (BHCS) and the
appropriate plastic spacer (see FIGURE 2).
FIGURE 2 Mounting the Camera and Lens
2. Zoom Lens Cameras: Allow 3⁄16in. (5mm)
clearance from the front face of the lens to the
front faceplate of the cradle during the
camera/lens assembly. This clearance provides
the necessary space for the lens to extend
outward when zooming. Secure both the camera
and the lens to the cradle with the 1⁄4-20 BHCS
and appropriate plastic spacer.

Camera/Lens Wiring
WARNING: Use only the cables specified
under INSTALLATION, Cable Requirements
for wiring of all cameras and lenses.
5.6.1 General
1. The dual male threaded portion of the three (3)
liquid tight fittings, two (2) NPT 1⁄2in., and
one (1) NPT 3⁄8in., located in the rear of the
cradle, are preinstalled to a specified torque
to prevent entrance of water. Do not remove
or loosen these parts. The two large fittings
are supplied with seal glands for cables
with diameters from 4.3mm to 11.9mm
(0.17in. to 0.47in.). The small fitting will
accept cables with diameters from
4.6mm to 7.9mm (0.181in. to 0.312in.)
see FIGURE 3.
Securely tighten all fittings to ensure a liquid-
tight seal. Failure to do so could allow water to
enter the housing and damage the camera and
lens.
FIGURE 3 Liquid Tight Fitting Assembly
If a sealant is to 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 a PG type conduit, an NPT to
PG Conversion Kit (LTC 9381/00) can be purchased
separately.
Use of drip loops is recommended on the
wiring outside of the rear endcap.
5.6.2 Plug Insertion
If no lens control or feed-through wiring will be used,
remove the preinstalled 3⁄8in. liquid-tight fitting from
the small bottom center hole and install the 3⁄8in. NPT
plug provided. Use a 8mm (5⁄16in.) hex wrench to
tighten. Failure to do so will allow water to enter and
cause damage to all electronic parts (see FIGURE 4).
