Camera/Lens Wiring
WARNING: Only use 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 liquid tight
fittings, two NPT 1/2-inch and one NPT 3/8-inch,
located in the rear of the cradle are provided pre-
installed. Do not remove or loosen these parts. They
have been installed to a specified torque to prevent
entrance of water. The two large fittings are supplied
with seal glands for cables with diameters from 4.3 mm
(0.17 in) to 11.9 mm (0.47 in). The small fitting will
accept cables with diameters from 4.6 mm (0.181 in) to
7.9 mm (0.312 in). See Figure 5 and 6.
Be sure to 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.

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 PG type conduit, a NPT to PG
conversion kit (TC9380PG) can be purchased
separately.
Use of “drip loops” is recommended on
the wiring outside of the rear end cap.
See Figure 7.

Plug Insertion
If no lens control or feed-through wiring will be used,
remove the pre-installed 3/8-inch liquid-tight fitting from the
small top center hole and install the 3/8-inch NPT plug
provided. Use a 5/16-inch (or 8 mm) hex wrench to tighten.
Failure to do so will allow water to enter and cause damage
to all electronic parts. See Figure 8.

Power Connections
The LTC 9380 Series housings offer the user one of three
transformer voltage configurations. The suffix to the
housing model number will determine the type of
transformer and supply voltage required.
The LTC 9380 Series allow the use of 24 VAC cameras
regardless of the supply voltage to the housing This is
achieved through the use of a transformer in the housing.
Each transformer provides a 24 VAC supply for the camera
power from its secondary. The transformer's primary supply
power will vary dependent upon the model housing, see
Model Designation. In the 115 volt and 230 volt models,
the transformer also supplies 24 VAC power to the integral
window heater/defogger.
Refer to the following model housing sections for your
model wiring procedure.
Power connection into the housings is to be supplied
through a minimum type UL Standard "SJ" cord acceptable
for outdoor use. Installation must conform to acceptable
NEC and local codes. Use the Recommended Maximum
Cable Lengths chart for selecting the proper wire size
used.
