b) the panel travels parallel to a flat surface at a distance of
100 < X ≤150 mm from it (see diagram), and the force of
the panels are within the permitted values
c) the secondary contact edge is covered by guards (such as
covers, casings or fixed panels) at a distance of ≤ 8 mm or ≥ 25
mm from the door panels, designed in such a way that:
- people are unable to reach any danger point up to a height of
2.5 m above the floor;
- they can only be removed or opened with the aid of a tool;
- they do not create additional risks (e.g. shearing or entrainment)
d) the secondary contact edge is covered by barriers at a
distance of ≤ 8 mm or ≥ 25 mm from the moving panels.
The barriers are installed to direct pedestrian traffic or prevent
pedestrians from accessing unsafe areas. They must be:
- designed in such a way that children cannot climb over or
slide underneath them, appropriately installed, capable of
withstanding the forces that occur during normal operation, at
least 900 mm tall. The barriers must not generate new hazards.
e) the protection measures regarding the danger of shearing
and conveying can be considered applied to the danger points
during the opening cycle if the safety distances indicated in the
figures are met
2.7 - Hazards and risks
The typical hazards which arise during closing of the door are as
illustrated below.
Bear in mind that different levels of risk may be associated with
shearing
crushing
3 - PRELIMINARY CHECKS
Before installing the product, check and verify the following points:
- Check that the door is suitable for automated control
- The weight and the size of the door must be within the limits of use
specified for the automation system in which the product is integrated
- Check that the mechanical safety stops required on the door are
solid and properly installed
- Check that the product fixing area is not subject to flooding
- Heavy acidity or salinity conditions or proximity to sources of heat
may cause product malfunction
- In case of extreme weather conditions (for example snow, ice, sudden
temperature changes, high temperatures) friction could increase and
consequently, the force necessary for movement and initial start-up
could be higher than that required under standard conditions

hazard
any one hazard:in fact, risk is the combination of the probability
that a hazard may occur (which increases in direct proportion to
the number of users) and the gravity of its consequences.

- Check that the manual movement of the door is smooth and free
from peak friction points and that there is no risk of the door going
off its rails
- Check that the door is well balanced and will not move notwithstanding
the position it is left in
- Check that the power line to which the product is to be connected is
equipped with an adequate safety earthing system and protected by a
magnetothermic circuit breaker and differential cutoff device
- Provide a disconnecting device in the system power supply network
with a contact opening gap that allows for complete disconnection in
the conditions provided by the overvoltage category III.
- Check that all the material used for installation complies with the
regulations in force
