PRELIMINARY CHECKS AND IMPORTANT INSTALLATION
INFORMATION
BEFORE INSTALLING THE PRODUCT PLEASE CHECK:
1. that the structure is in good working order (posts, hinges, gate leaves) in relation to the power generated by the
motors.
2. that sufficiently robust mechanical travel limits have been installed at the gates opening and closing points.
3. that there is no friction or excessive spaces between the lower castors/wheels and the upper roller/guide system.
4. that the original manual locking system has been excluded.
5. that all electrical wiring and cables are in good working order.
Important warnings:
1. The installation of the automation must be carried out correctly by professionally qualified personnel in
conformity with the machine directive 98/37/CE and the standards EN13241-1, EN 12453 and EN 12445.
2. Carry out risk analysis of the closing system and the solutions used and adopt all necessary security and visual
warning devices.
3. Install the command devices (e.g. selector switches) in such a way that the user cannot find himself in dangerous
positions.
4. Apply a CE panel or adhesive to the installation containing all danger information and the installation
identification data.
5. Make sure the operating instructions, general warnings for a safe installation and the CE conformity declaration
have been given to the end user.
6. Make sure that the end user has correctly understood the automatic, manual and emergency operations to be
carried out.
7. Once the installation has been completed, carry out a series of tests to make sure that the
safety devices, warning signals and release mechanisms are all working correctly.
8. Write the following information down for the user (in the instruction manual for example):
a. the presence of any residual risk factors that have not been protected and factors that could arrive from
unforeseen use of the system.
b. The end user must disconnect the mains power supply before releasing the gate, carrying out ordinary
maintenance intervention or attempting to clean the area of the installation.
c. The end user must frequently check the installation for visible signs of damage and immediately inform the
installer should any arise.
d. Make sure that the end-user is aware that children must not be allowed to play within the area of an automatic
installation and that radio control devices and other command devices are kept out of their reach.
9. Draw up a maintenance plan for the installation (at least every six months) and write the interventions carried out
in a maintenance register.
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 mm2.
2) signal section (controls, safety contacts, auxiliary power supply) minimum wire section 0.75 mm2 - 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.
✓ All N.C. inputs (normally closed) not used in the control unit must be shorted with the common.
✓ All N.C. contacts associated with the same input must be connected in series.
✓ All N.O. contacts (normally open) associated with the same input must be connected in parallel.
✓ For the control unit power supply, the INSERTION OF AN EXTERNAL DISCONNECT SWITCH (not
supplied) is envisaged, which must be independent and sized according to the load.
