according to the regulations in force.
• Before moving or carrying out technical
operations on the unit, isolate and disconnect
it from the power supply.
• Do not use worn or damaged power cords,
since they represent a serious risk for the

• The installation of the unit (and the associated
equipment of which the unit is part) must be
carried out by adequately skilled technical
personnel.
• Do not use the device in areas containing
inflammable substances.
• Make sure that the unit is mounted securely
using fixings adequate for the weight and the
mounting surface.

INTRODUCTION
Weatherproof housing for CCD camera, entirely
constructed of stainless steel, enclosed by 2 heavy
duty flanges. The back flange allows the cables
to run though 4 PG13,5 cable glands. Made of
AISI 316 stainless steel, it is particularly designed
for marine and industrial environments where the
external agents are highly corrosive.
m
T h e e l e c t r i c a l i n s t a l l a t i o n
operations must only be carried
out by qualified personnel, according to
the laws and regulations in force. Turn
off the power before performing any
operation.

Cleaning IR glass
We recommend using neutral soap diluted in
water.
m
When cleaning the window with
the IR filter, take extra care not
to scratch or damage the outer surface
treated with carbon coating. Damage to
this coating could also interfere with the
transparency of the surface to infrared
light. Do not use ethyl alcohol, solvents,
hydrogenated hydrocarbons, strong acids
or alkalis. These products will irreparably
damage the surface of the IR glass and
the plastic parts.
INSTALLATION
How to open the housing
To open the housing unscrew the bolts on the
bottom flange (Fig. 1) using the hexagonal
spanner supplied. The access into the housing can
be both from the back flange and from the front
one. When the housing is opened remove the
slide block (Fig. 2, point 2) and slip off the inner
slide using the relevant fixing slit (Fig. 2, point 3).
m Opening the housing from the
frontal flange pay attention to the
PTC heating (see the marks shown on the
labels).
How to install the camera
This chapter described how to install the camera
into the housing.
1. Open the housing as described previously.
2. Fit the camera on the slide, using the insulating
plate and the supplied 1/4” screw (Fig. 3). If
necessary, use the spacers to position the
camera and optics correctly.
3. Feed the cables through the cable grip, and
make the necessary electrical connections,
ensuring that the cable grips are holding
firmly.
