4. INSTALLATION REQUIREMENTS

4.2 ELECTRICAL SYSTEM

4.1 MECHANICAL REQUIREMENTS

Always shut off the power supply before performing any work. If the

disconnect switch is not in view, apply a warning sign stating “WARNING -

Maintenance in Progress”.

The electrical system must comply with applicable legislation in the country

of installation.
Use components and materials with CE marking which are compliant with the

Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU.
The power supply line for the automation must be fitted with a multi-pole cir-

cuit breaker, with a suitable tripping threshold, a contact opening distance of

at least 3 mm and a breaking capacity that complies with current regulations.
The power supply for the automation must be fitted with a 30 mA differential

switch.
The metal parts of the structure must be earthed.
Check that the protective earthing system complies with applicable regula-

tions in the country of installation.
The electrical cables of the automation system must be of a size and insulation

class that is compliant with current legislation and laid in appropriate rigid

or flexible conduits, either above or below ground.
Use separate conduits for the power supply and the 12-24 V control devices

/ accessories cables.
Check buried cable plans to ensure that there are no other electrical cables

in proximity to the planned digging/drilling locations to prevent the risk of

electrocution.
Check that there are no pipes in the vicinity as well.
The conduit fittings and the cable glands must prevent the entry of moisture,

insects and small animals.
Protect extension connections using junction boxes with an IP 67 protection

rating or higher.
The overall length of the BUS cables must not exceed 100 m.
It is recommended to install a flashing light in a visible position to indicate

when it is moving.
For the creation of detection loops, refer to the relative instructions.
The control accessories must be positioned in areas that are always accessible

and not dangerous for the user. It is recommended to position the control

accessories within the field of view of the automation. This is mandatory in

the case of hold-to-run controls.
The hold-to-run controls in the dead-man mode of operation, must comply

with standard EN 60947-5-1.
If an emergency stop button has been installed, it must be EN13850 compliant.
Comply with the following heights from the ground:
- control accessories = minimum 150 cm
- emergency buttons = maximum 120 cm
If the manual controls are intended to be used by disabled or infirm persons,

highlight them with suitable pictograms and make sure that these users are

able to access them.

The mechanical structural components must comply with the require-

ments of EN 12604. Before installing the automation, the suitability

of the mechanical requirements must be established and any work

that is necessary in order to meet them carried out.
The essential mechanical requirements are as follows:

Solid ground to support the weight of the gate, the structures present and

the gearmotor. Flat, horizontal paving in the area of movement of the

leaf. There must be no chance of water accumulating in the installation area.
The structure (columns, guides, mechanical stops, leaf and counterweights)

must be solid and there must be no risk of detachment or collapse (considering

the weight of the leaf and the forces applied by the gearmotor and wind

action). Perform structural calculations where necessary.
The structure must show no signs of corrosion or cracking.
The leaf must remain vertical throughout the entire length of travel, with a

regular, smooth and uniform movement. The path along which the leaf slides

must be perfectly horizontal (the leaf must not have a tendency to open or

close spontaneously when it is released).
Appropriate devices must be installed to prevent the leaf from falling.
There should be a solid surface on the leaf sufficiently large to attach the

rack to.
The sliding guides must be in good condition; they must be straight and not

deformed, they must be fastened securely and there must be no obstacles

along their entire length. The diameter of the guide wheels must be

appropriate for the weight and length of the leaf and their profile section

must coincide with that of the sliding guide. The number and position of

the wheels must ensure an adequate and constant distribution of the weight.
A solid guide system for the suspended leaf in the case of a cantilever gate.
Presence of upper containing guide to prevent vertical oscillation of the

leaf. The leaf must not under any circumstances come out from its guides

and fall. Wheels, rollers and bearings in good condition, lubricated and

free from play or friction.
Presence of external mechanical limit stops to limit the travel of the leaf

when opening and closing. The stops must be suitably sized and solidly

fastened so that they resist any impact of the leaf in the event of improper

use (leaf pushed and left to slide freely). The mechanical limit stops must

be positioned at 50 mm beyond the stop position of the leaf, and must ensure

that the leaf remains inside its sliding guides.
The thresholds and protrusions of the paving must be appropriately shaped

in order to prevent the risk of sliding or slipping.
For the creation of detection loops, refer to the specific instructions.
Presence of a safety area between the wall (or other fixed element) and the

furthest protruding part of the open leaf, to protect against the risk of persons

becoming trapped/crushed. Alternatively, check that the opening force

required falls within the maximum permissible limits according to applicable

standards and legislation.
Presence of safety areas between the fixed and moving parts, to protect

against the risk of hands being trapped. Alternatively, apply protective

elements that prevent fingers from being introduced.
Presence of a safety area between the paving and lower edge of the leaf, along

its entire path, providing protection from the risk of feet becoming caught in

and crushed beneath the wheels. Alternatively, apply protective elements

preventing the introduction of feet.
No sharp edges or protruding parts should be present to ensure there are no

cutting, hooking or perforation hazards. Alternatively, eliminate or protect

any sharp edges and protruding parts.
No slots or openings should be present on the sliding leaf or the fencing to

prevent the creation of a shearing hazard. Alternatively, apply protective
