C) – Installation
1) Unscrew the cover screws and lift the cover. Check that the electronic unit is in good order. In case of doubt do not install the unit and ask for
the intervention of qualified personnel. The container's accessories (screws, round seal, cable glands) must not be left within the reach of
children since they are a potential danger.
2) Check that the electronic unit is properly fixed to its box. If not, tighten all screws or provide the missing screws.
3) Place the unit near the gate so that the system connection wires' length is reduced to the minimum.
Caution: For the unit's correct operation the wires connected to it must not be longer than 10 metres.
4) For increased weather protection we recommend to place the unit under a roof or, even better, in an enclosure having two side walls.
Wherever possible, it is advisable to install the unit at a minimum 1,5 mt level above the ground to keep it out of the reach of children.
5) Before proceeding to assembly place the container so that the side fitted with the cable glands is directed towards the ground.
Caution: Do not assemble the container on wood surfaces.
6) Insert the supplied round seal in its seat. Make sure the two ends meet at the centre of the side to which the cable glands are fitted.
7) Lift the mobile portion of the connector and proceed to connect the unit wires as described in the following chapters.
