3.2. Preliminary checks

To ensure a correct operation of the automated system, make sure
the following requirements are observed as for the gate structure
(existing or to be created):
• the mechanical parts must conform to the provisions of Standards
EN 12604 and EN 12605.
• leaf length in compliance with the operator specifications.
• sturdy and stiff structure of the leaves, suitable for automation
• regular and uniform movement of the leaves, without any friction
and dragging during their entire opening
• stiff hinges in good conditions
• presence of both opening and closing mechanical limit stops
• presence of an efficient earthing for electrical connection of
the operator
Perform any necessary metalwork job before installing the
automated system.
The condition of the gate structure directly affects the reliability
and safety of the automated system.

3.3. Installation dimensions

Determine the fitting position of the operator with reference to
Fig. 4.
Check with care if the distance between the open leaf and any ob-
stacles (walls, fences etc.) is higher than the operator dimensions

eneRal Rules to deteRmine the installation dimensions
• to obtain 90° leaf openings : A+B=C
• to obtain leaf openings exceeding 90° : A+B<C
• Smaller A and B dimensions determine higher peripheral speed
of the leaf.
• Limit the difference between A and B dimension within 4 cm:
higher differences cause great speed variations during the gate
opening and closing movement.
• Keep a Z dimension in such a way that the operator does not
strike the pillar.
• in the LS versions the limit switches are triggered for the first and
the last 30 mm. Therefore use such A and B dimensions in order to
use the whole operator travel. Shorter travels could limit or cancel
the limit switch adjustment range.
If the pillar dimensions or the hinge position do not allow the installa-
tion of the operator, a niche on the pillar, as shown in Fig. 5, should
be created in order to maintain the A dimension as determined.
The niche should be dimensioned in such a way to enable easy in-
stallation, operator rotation and operation of the release device.
3.4. Installing the operators
Fix the rear bracket in the position determined before. In the
1.
event of iron pillar carefully weld the bracket directly on the
pillar (Fig. 6). In the event of masonry pillar, use the suitable
plate (optional) for the fixing to screw (Fig. 7) by making use
of suitable fastening systems. Then carefully weld the bracket
to the plate.
During the fastening operations, check if the bracket is per-
fectly horizontal by means of a level.
2. Assemble the rear fitting to the operator as shown in Fig. 8.
Set the operator for manual operation (see paragraph 5 )
3.
4. Completely extend the rod till it reaches the limit stop, fig. 9
ref. a.
5. Lock the operator again (see paragraph 5.1 )
6. Turn the rod clockwise half a revolution / a revolution, Fig. 9
ref. b
7. Assemble the front bracket as shown in Fig. 10.
8. Fix the operator to the rear bracket by means of the supplied
pins as shown in Fig. 11.

170 390 110 60 1290
Before fastening the operator on the bracket you have just
welded, wait for the bracket to cool.
9. Close the leaf and, keeping the operator in a perfect horizontal
position, determine the fastening point of the front bracket
(Fig. 12).
10. Temporarily fix the front bracket with two welding spots (Fig.
12).
If the gate structure does not allow a fix bracket fastening it
is necessary to create a sturdy supporting base in the gate
structure.
11. Release the operator (see paragraph 5) and manually check
if the gate can completely open without hindrances and stop
at the mechanical travel stops as well as if the leaf moves
regularly without any friction.
12. Carry out the necessary corrective measures and repeat from
point 8.
13. Temporarily release the operator from the front bracket and
weld the bracket definitively.
If the leaf structure prevents the bracket from being welded,
screw it to the leaf with adequate securing systems. There-
fore, act as we explained before.
We recommend to grease all the fastening pins of the fittin-
gs.
3.5. Wiring the operator
E
c
A terminal board is fitted in the lower part of the operator for the
45
connection of the motor, of any limit switch and for the earthing
of the operator.
45
To connect the motor, the supplied cable must be used for
the mobile section, or a cable for mobile laying from the
outside.
Motor wiring operations:
1. Open one of the two pre-drilled holes in the supplied cover, Fig.
13; in case of operators with limit switches, open both holes.
2. Fit the supplied cable gland.
3. Connect the motor and the earthing with reference to Fig. 14
and the following tables.

To maintain approval for CSA-UL approved operators, position
the capacitor (secured in a stable manner) inside a CSA-UL
approved enclosure.
4. Close the cover with the four supplied screws, Fig.15.

3.6. Limit switches

"LS" models are equipped with opening and closing limit switches.
Therefore they require the use of a control board able to control
these inputs.
Limit switches are triggered for the first and the last 30 mm
of the travel. Therefore the operator should use the whole
available travel during the opening phase. Shorter travels
can limit or completely cancel the limit switch adjustment
range.

iRing the limit sWitChes
Limit switches are wired in the same terminal board where the motor
wiring has been carried out. Wire the limit switches as follows:
Open the second pre-drilled hole in the cover, Fig. 16.
