tests during installation.
INSTALLATION
The equipment must be installed "PROFESSIONALLY" by personnel with qualifications as envisaged by current
legislation and incompliance with the standards EN12453 and EN12445 governing safety of the automation.
- Ensure that the automation is equipped with end stops and that these are correctly sized to suit the overall weight
of the gate.
- Fix the control unit on a flat and immobile surface, suitably protected against the risk of impact and flooding.
ELECTRICAL CONNECTIONS
For connections, refer to table 2 and figure 2.
In the case of existing systems a general check should be made of the condition of wiring (section, insulation, contacts)
and auxiliary equipment (photocells, receivers, push button panels, key-operated switches etc.).
A number of recommendations for a correct electrical installation are listed below:
- wiring entering the sealed box of the control unit must maintain, when possible, the initial protection rating of IP56.
- The section of the cables must be calculated on the basis of their length and maximum current.
- Do not use a single "multi-pole" type cable for all connections (line, motors, controls etc.) or in common with other
equipment.
- Divide the system into at least two sections, for example:
1) power section (power supply line, motors, flashing light, courtesy light, electric lock) minimum wire section 1.5 mm
2
(motorline 2.5 mm
2) signal section (controls, safety contacts, auxiliary power supply) minimum wire section 0.75 mm
- When very long control cables are used (over 50 metres) decoupling is recommended by means of relays installed
in the vicinity of the control unit.

9 Control unit reset (momentary short-circuiting of the
2 pins has the same effect as switching the control
unit off and back on)
10 Step-by-Step pushbutton (P/P)
11 Input status signalling Led. Led ON = input closed;
led OFF = input open
12 Terminal boards for connection of controls, safety
devices and auxiliary circuits power supply.
13 Trimmer for motor torque adjustment (mod. T31)
