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.
The EX FIX IR illuminator emits an high intensity IR light. Wear protective eyewear.
Avoid direct eye and skin exposure. Please follow safety precautions given in IEC
