4 INSTALLATION
These units contain a high performance camera,
prepackaged in an environment-resistant, sealed
housing, pressurized with dry nitrogen. The cameras
themselves are automated to a high degree, and
factory-adjusted for optimum performance under
foreseeable conditions of use. In normal conditions, No
initial or early life adjustments should be necessary.
The units provide reliable, unattended, continuous
performance in a wide variety of applications.
4.1 Cable Routing
CAUTION: Be sure cable wires do not pinch or rub
when connected to pan/tilt units. Frayed, pinched, or
broken wires can cause fire or shock hazards, or
system failure.
4.2 External Synchronization
See WIRING DIAGRAMS and individual camera
instructions for external synchronization capabilities.
4.3 Phasing
The phase lock loop circuit controlling the sync
generator synchronizes the camera to the power line
zero crossing. This feature improves vertical interval
switching and time lapse recording. To obtain full
benefit of this feature, all cameras must be generated
on the same phase power. In low voltage (Class 2)
systems where the 24VAC wires may easily be
reversed, color coding is recommended to maintain
correct power line phasing.
4.4 Mounting
Mount the camera using two or more of the
1/4-20 threaded holes in the base. The support system
should give adequate consideration to the camera
weight involved, as well as any additional loading from
snow, ice, and wind. The camera cradle itself may be
rotated with respect to the housing. This rotates the
camera and the resulting picture. For accurate
positioning, align the index marks on the rear end-cap
with the alignment marks on the housing. There are
four alignment marks spaced at 90
°
intervals on the
housing. See FIGURE 2.
If the camera is located where it is exposed to direct
sunlight, the LTC 9384/00 accessory sunshield should
be and attached (ordered separately).

4.5 Electrical
All electrical connections are made via the single
corrosion-resistant connector on the rear panel. A
mating connector and crimp pins are supplied. The
pins accept wire from a minimum of 0.5mm
2
(20AWG) to a maximum of 1.5mm
2
(16AWG). Crimp
the wire to the connector using an appropriate crimp
tool. See WIRING DIAGRAMS for pin connections.
Information on sync and video hookups is given in the
basic camera instructions. Zoom lens models require a
zoom lens control system.
