Installation manual v4
8-66
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.
Earth ground attachment point is a stud M4-0.7 x16 A4-70 ISO 4762 with dual nut and
dual serrated washer.
During installation it is important to connect it to an appropriate grounding location using
a (minimum) 6 mm
2
(10 AWG) copper stranded wire.
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. The switch must be
equipped with protection against the fault current towards the ground (differential) and
the overcurrent (magnetothermal, maximum 15 A). Recommended for 115 Vac / 230
Vac: 2 A Delayed Fuse T (Time delay) or equivalent resettable devices such as
magnetothermal. Recommended for 24 Vac: 4 A Delayed Fuse T (Time delay) or
equivalent resettable devices such as magnetothermal. These ratings include inrush
current for startup or temporary overload. It must be very quickly recognizable and
readily accessible. Install a suitable overcurrent protection.
For connection to the mains, use a multipolar cable having minimum 3x1,5 mm
2
(15
AWG). The mains cable must be protected.
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.
Make sure that the unit case is properly earthed, connecting all the earth ground studs.
Earth cable should be about 10 mm longer than the other cables on the connector, in
such way that it will not be accidentally disconnected if the cable is stretched or pulled.
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.
Make sure the threads of the unit are free of dirt and debris. A minimum of 10 mm depth
and 5 threads of engagement must be maintained for all threaded holes.
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.
It is strongly advised to perform and test all the connections on a safe area laboratory
before installing on field.
Remove the protective PVC sheet from the sunshield in a non-explosive atmosphere
before installation
The EX PTZ D-IR emits an high intensity IR light. Wear protective eyewear. Avoid direct
eye and skin exposure. Please follow safety precautions given in IEC 60825-1 and IEC
62471.
