FOR THE MOTORISATION OF SLIDING GATES
IN ACCORDANCE WITH MACHINERY DIRECTIVE 98/37/EEC AND THE APPLICABLE PARTS OF
STANDARDS EN 13241-1, EN 12453, EN 12445
With this publication UNAC sets out to inform and assist installers in applying the specifications of the directives
and of European standards concerning the safe use of motorised gates/doors.
It should be noted that those who sell and motorise an existing manual door/gate become the manufacturer of the
motorised door/gate machine and must prepare and keep the technical file, as laid down by Annex V of the
Machinery Directive (98/37/EEC). The technical file must contain the following documents:
 Assembly drawing of the motorised door/gate (usually included in the installation manual).
 Electrical connections and control circuit diagrams (usually included in the installation manual).
 Risk analysis including (as indicated on the following pages):
the list of the essential requirements as indicated in Annex I of the Machinery Directive;
the list of the risks presented by the door/gate and the description of the solutions adopted.
 They must also keep the manuals for installation and maintenance of the door/gate and of the components.
 Prepare the operating instructions and general warnings for safety (if necessary integrating those in the manual
for installation of the door/gate) and give the user a copy.
 Compile the proof book and give the user a copy (see facsimile in Annex 1).
 Draft the EC declaration of conformity (see facsimile in Annex 2) and give the user a copy.
 Fill in the label or plate with CE marking and attach it to the motorised door/gate.
N.B. The technical file must be held and made available to the competent national authorities for at least ten years
from the date of construction of the motorised door/gate.
Note also that, as from May 2005, the manufacturer of a new door/gate (both manual and motorised) must observe the
procedure for the CE marking pursuant to the Construction Products Directive (89/106/EEC), as indicated in annex ZA of the
standard EN 13241-1. This procedure involves the manufacturer:
 setting up and maintaining internal production control;
 having a notified body carry out the initial type tests referring to the applicable characteristics indicated in Annex ZA of
standard EN 13241-1.
N.B. UNAC is preparing guidelines dedicated to the correct application of the Construction Products Directive (89/106/EEC).

Mechanical risks caused by the movement of the gate (see references in Figure 1).
FCAUTION – If the door/gate is used solely with hold-to-run controls (and meets the requirements of the
standard EN 12453), the danger points listed below do not have to be protected.
FCAUTION – If protective devices are installed (in accordance with the standard EN 12978) which prevent in
all cases contact between the moving leaf and persons (for example photoelectric barriers, presence sensing
devices), it is not necessary to measure the operating forces.
[3] Impact and crushing on the main closing
edge (Figure 1, risk A).
FMeasure the closure forces (by means of the
special instrument required by the standard EN
12445) as illustrated.
Check that the values measured by the instrument
are below those indicated in the graph.
Carry out the measurements in the following points:
L = 50, 300 and 500 mm;
H = 50 mm,
at mid-height of the leaf and
at the height of the leaf minus 300 mm (max
2500).
N.B. The measurement should be repeated three
times in each point and the average value
considered.
The graph indicates the maximum values of the
dynamic, static and residual operating forces in
relation to the various positions of the leaf.
N. B. With reference to the measurement points with
L = 50, 300 and 500 mm, the maximum dynamic
force value permitted is 400 N.
FIf the values of the forces are higher, install a
protective device in accordance with the standard
EN 12978 (for example a sensitive edge) and repeat
the measurement.
N. B. The dynamic force can be reduced, for
example, by reducing the speed of the leaf or using
a sensitive edge with high elastic deformation.
[4] Impact on the main closing edge (Figure 1,
risk A).
FTo reduce the risk of impact between the sliding
leaf and persons (or vehicles), a pair of photocells
must be installed (preferably on the outside) as
illustrated (recommended height 500 mm).
FIn the cases where the thickness of the leaf is
greater than 150 mm, or when the impact risk is high
(such as for example the presence of unattended
children), a second pair of photocells should be
installed (on the inside), as illustrated (recommended
height 500 mm).
N.B. The test specimen for presence sensing is a
parallelepiped (700 x 300 x 200 mm) having 3 faces
with a light and reflective surface and 3 faces with a
dark and opaque surface.
