Installation of the unit
Make sure that the installation surface can support at least four times the weight of
the unit in normal operating conditions. In case of excessive external stress
(vibration, strong winds or impact, for example), the equipment may need
additional means of protection.
Proper stainless-steel hardware (grade A4 or 316) should be carefully chosen to
fasten the unit to the surfaces. Proper tools should be used during the installation,
in accordance to environmental requirements.
Dome covers should be opened only by the manufacturer.
Electrical connections (such as plugs and cords) must be protected from potential
hazardous environmental factors (e.g. foot traffic, hitting objects).
Pointing the camera at the sun may damage it.
Complete the installation performing the camera connection referring to the
manual of the camera.
Carefully check the supply voltage marked on the label. An incorrect power supply
voltage may damage the unit. Do not overload the terminal connection, as it may
cause a fire or electrical shock hazard.
To protect the installation for overcurrent, install a delayed fuse T (Time delay) of
at least 4 A or fuse of 10 A max. Or equivalent resettable devices such as
magnetothermal fuses. These ratings include inrush current for startup or
temporary overload. It must be very quickly recognizable and readily accessible.
For connection to the 24Vac use a multipolar cable having minimum 3x1,5 mm
2
(15 AWG). The mains cable must be protected.
An all-pole mains switch with an opening distance between the contacts at least 3
mm in each pole must be incorporated in the electrical installation.
Make sure that the unit case is properly earthed. The Protective Earth (PE)
connection is included in the 3p or 5p power connector. The minimum wire size is
2.5 mm
2
copper stranded wire.
Fasten all the cables inside the housing with cables ties or other fixing means to
avoid the electrical contact with surrounding parts in case cables get loose.
Do not connect the unit to a supply circuit unless the installation is completed
To maintain the certification requirements and the IP rating of the unit, adequate
certified cable glands must be used. Each unused cable gland hole must be
closed using a proper plug suitable for the housing marking.
Check the proper position of the O-ring seals in their groove
Keep the unit tightly closed when operating.
Disconnect the equipment from the supply circuit and wait at least five minutes
before opening.
