4.1 Product description and type
designation
This housing has been designed to t thermal
cameras with large lenses for vision even in total
darkness, fog, rain and smoke, or for long distances.
It can be used for a wide range of day/night
surveillance systems, such as monitoring and
rescue in the event of a re, public safety or airport,
industrial and environmental surveillance.
The opening system allows an easy access for
installation and servicing.
It can be installed with cable sheaths, instead of
regular cable glands using the junction box for the
wiring harness.

5.1 Safety precautions before use
CAUTION! The electrical system to which
the unit is connected must be equipped
with a 15A max automatic bipolar circuit
breaker. The minimum distance between
the circuit breaker contacts must be
3mm (0.1in). The circuit breaker must be
provided with protection against the fault
current towards the ground (dierential)
and the overcurrent (magnetothermal).
5.2 Unpacking
When the product is delivered, make sure that the
package is intact and that there are no signs that it
has been dropped or scratched.

Tab. 11Dierent alternatives are available depending on the
version. VOUT = 12Vdc o VOUT = 24Vac, in relation to the
type of power supply installed (7.2.1 Camera power
supply installation, page9). VOUT = VIN, only for housings
powered in 12Vdc or 24Vac, with jumper inserted (J5).

Nominal section of the cables used: from
0.2mm² up to 2.5mm².
6.4 Connection of the power
supply line
CAUTION! The type of cable used must be
compatible with the planned use. Comply
with the national regulations in force on
electrical installation.
Connect the safety earth to the relative
terminal of the power supply connector.
Earth cable should be about 10mm longer
than the other two, so that it will not be
disconnected accidentally if pulled.
Insert the cables inside the housing using the cable
glands. The cable glands are suitable for conductors
with diameters of between 5mm and 10mm. The
section of the cable inside the housing must be
suciently long to allow connection. Suitably lock
the cable glands.
