Final Assembly - Moog Videolarm AD16CH2 Product Instructions

LIQUID TIGHT FITTINGS
The dual male threaded portion of the three liquid tight fi ttings, two
NPT 1⁄2-inch, and one NPT 3⁄8-inch, located in the rear of the cradle,
are provided preinstalled. Do not remove or loosen these parts. They
have been installed to a specifi ed torque to prevent entrance of water.
The two large fi ttings are supplied with seal glands for cables
with diameters from 4.3 mm (0.17-inch) to 11.9 mm (0.47-inch). The
small fi tting will accept cables with diameters from 4.6 mm (0.181-
inch) to 7.9 mm (0.312-inch) (Figure 4).

CAUTION: Be sure to securely tighten all fi ttings 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.
NOTE: Use of drip loops is recommended on the wiring
!
outside of the rear end cap.
If no lens control or feed-through wiring will be used, remove the
preinstalled 3⁄8-inch liquid-tight fi tting from the small bottom 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 (Figure 5).

WIRING
1. Use the left liquid-tight fi tting of the housing to route the power wire
into the housing.
2. A screw/terminal lug is provided for securing a safety ground.
Attach the terminal lug to the cradle using the M4 x 10 screw
provided (Figure 6).

4. Install the seal cap portion of the large liquid tight fi tting on the
video coax cable and pull the cable through the right fi tting on the
rear end of the cradle. If lens control is used, pull cable through the
small bottom fi tting.
5. Attach the BNC connector to the coax and connect it to the
camera. Pull any excess wire out of the cradle assembly and
tighten approximately 1 to 11⁄2 turns past the point where the
fi tting starts to grip the wire. Failure to do so will result in water
damage to all electronic parts. Use a tie wrap (included) to provide
strain relief on the video cable at the exit point (inside unit).
6. Install the 3⁄8-inch NPT plug provided in the unused, small top
center NPT hole.
CAUTION: Be sure to securely tighten all fi ttings to
!
ensure a liquidtight seal. Failure to do so
could allow water to enter the housing and
damage the camera and lens.

FINAL ASSEMBLY

CAUTION: If the breather hole is open, do NOT mount
!
the housing in a position where the front end
cap is pointed upward.
To maintain enclosure protection ratings of NEMA-6P and IP68, the
pull seal (provided in the hardware kit) must be installed in the front
end cap. It is recommended that the pull seal be installed in a cool,
dry environment to prevent trapping moisture inside the housing
(Figure 7, next page).
NOTE: Pull seal installation allows the housing's front end cap to be
pointed upward.
