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.

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 6.
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 7.

5.8.1 Supply Power Connections
The HS9385 Series housings offer the user one of three
voltage configurations. The suffix to the housing model
number will determine the supply voltage required.
Any camera installed in the HS9385 Series housings
must be of the same voltage type as the housing. The
integral heater/defogger also requires the same voltage as
the housing. These housings do not contain step down or
isolation transformers. See the
Model Designation
chart
for suffixes and supply voltages required.
