Evaluation criteria and solutions to be adopted
(Tick the box corresponding to the solution adopted)
1.3.7
1.3.8
1.4
Mechanical risks due to
movement of the leaf.
[7] Dragging of the hands
in point (Figure 1, risk D).
[8] Dragging of the feet on
the lower edge (Figure 1,
risk E).
[9] Dragging of the hands
on the drive unit (Figure
1, risk F).
F Check that there is a clearance ≤ 8 mm.
or:
F attach guards that prevent fingers from being inserted (for example a rubber
strip).
F The clearance between the gate and ground must prevent the risk of
dragging of the feet.
F Adequately protect the point of dragging between the pinion and the rack
during movement of the leaf.
1.5.1
1.5.2
1.5.10
1.5.11
Electrical and
electromagnetic
compatibility risks
[10] Direct and indirect
contacts.
Dispersion of electrical
energy.
[11] Risks relating to
electromagnetic
compatibility.
F Use CE-marked components and materials pursuant to the Low Voltage
Directive (73/23/EEC).
F Carry out the electrical connections, connection to the mains, earth
connections and relevant checks, in accordance with current regulations and as
indicated in the installation manual of the drive unit.
N.B. If the electrical supply line is already set up (via both a socket and a
connector block) declarations of conformity to Italian law no. 46/90 are not
necessary.
F Use CE-marked components pursuant to the EMC Directive (89/336/EEC).
Carry out the installation as indicated in the manual for installation of the drive
unit.

1.5.3
1.2.3
1.2.4
Safety and reliability of
drive unit and control and
safety devices.
[12] Safety conditions in
the event of
malfunctioning and power
failure.
[13] Energy types other
than electrical energy
[14] Actuation and
disabling of the drive unit.
[15] Power supply switch.
F Use drive units which comply with the standard EN 12453 and safety devices
which comply with the standard EN 12978.
F If hydraulic drive units are used, they must comply with the standard EN 982;
or
F if pneumatic drive units are used, they must comply with the standard EN
983.
F Check that, after a fault or power failure, the drive unit restarts safely without
creating hazardous situations.
F Install an omnipolar switch for electrical insulation of the door/gate, in
accordance with current laws. This switch must be positioned and protected
against accidental or unauthorised actuation.
