F
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.
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.
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
mesh to any such openings. The mesh should be sufficiently fine to prevent
introduction of body parts requiring protection, in relation to the distance
between the fixed and moving parts.
For the minimum dimensions to prevent crushing/shearing of body parts,
refer to EN 349. For the safety distances required to prevent danger zones
being reached, refer to ISO 13857.
If the area of installation gives rise to the risk of impact by vehicles, provide
an appropriate protective structure to protect the gearmotor.
