2) INSTALLATION INSTRUCTIONS:

When installing the gearmotors strictly follow all the instructions given in the relevant instruction manuals. It is necessary to
underline that the gate must be equipped with the necessary mechanical travel stops which are essential for the correct
functioning of the "Travel limit search" and are required in order to comply with point 5.2.1 of the prEN 12453
Do not install the unit without the "Mechanical travel stops"!
These mechanical stopping devices must be able to stop gate movement under any conditions. Make absolutely certain that
the mechanical stop is able to withstand and absorb, without any deformation whatsoever, all the kinetic energy accumulated
by the gate's movement!
We advise verifying that the reaching of the mechanical stop point does not lead to hazardous situations and that the safety
margins are always complied with!
Do not install the unit if you have not read all the instructions of the unit and the actuators!
Before starting installation, verify that the gate to be automated is in a sound condition and that the mechanics are in good
working order and observe the safety margins and minimum distances.
Carefully analyse all the risks relating to the automation you are about to install, evaluate with particular care the safety devices
to be installed and always install an emergency stop device, which should be a category 0 stop device.
Remember that there are specific requirements to be strictly observed regarding both the safety of electrical installations and
automatic gates!
As well as the legal requirements and standards that must be adhered to, please take note of the following points to ensure
maximum safety and reliability in your installation:
• The power line to the unit must always be protected with a circuit breaker or a pair of 5A fuses, an RCD is recommended but
not essential if there is already one on the mains supply.
• Power the unit with a 3 x 1.5 mm2 cable (phase + neutral + earth). If the distance between the unit and earth connection
exceeds 30 m, install an earth plate near the unit.
• If the motors have no cable use a 5 x 0.75 mm2 type (Motor +, Motor -, Encoder, Encoder, earth). These cables must never
be longer than 3 m.
• Avoid, at all costs, connecting cables in buried boxes even if they are completely watertight.
• When connecting the low safety voltage part use wires with an 0.25 mm2 minimum cross section. For the electric lock only
use a wire with a cross section of at least 1.5 mm2. Used screened wire if length exceeds 30 m, earthing the braided wire only
on the unit side.
• Always and only use cables (individually insulated wires plus an additional general insulation) and never single wires even if
they are protected inside ducts.
Make sure you have all the material needed and that it is suitable for this kind of use.
