INSTALLATION OF THE REAR FIXING
BRACKET
Calculate the rear bracket position using CHART 2.
This chart is used to define distances A and E and the maximum
opening angle of the gate leaf.
Important - Distances A and E must be similar, to ensure a
linear automation movement.
We suggest that the values inside the recommended installation
area are used; only consider the maximum installation area if
staying within the recommended values is not possible.
FIG.2
A
C
E
1. Measure value E, and then trace a straight horizontal line by
that value.
2. Select a point in the line, taking into account the desired
opening angle, suitable for the column.
Trace a straight vertical line starting from the identified point,
and obtain value A.
3. Before proceeding with the installation, make sure that value
A allows to fix the rear bracket, otherwise select another point
on the chart.
4. Lastly, to fix the bracket move the piston to the limit of the
stroke (see Fig. 2).
CAUTION: Failure to comply with the bracket installation
distances may lead to automation operation faults, such as:
- Cyclical movements and accelerations at some positions
of the stroke.
- Increased motor noise.
- Limited opening, or no opening at all (in case of counter-
lever fixed motor).
5. Before it can be fixed to the wall, the bracket must be welded
to the fastening plate (Fig. 3); the bracket may be cut to the
desired length, adjusting distances A and E accordingly

NOTE - The bracket supplied with the gearmotor is 180 mm

WARNING! – Before fixing the rear bracket, make sure
that the front bracket will be fixed to a solid position of
the gate leaf; the front bracket will have to be secured at a
different height than the rear bracket (Fig. 4).

6. Fix the bracket in place using suitable plugs, screws and
washers (not supplied)
INSTALLATION OF THE FRONT FIXING
BRACKET
1. For the installation of the front bracket to the gate leaf, refer
to distance D (fig. 2).
2. Define the front bracket installation height in accordance with
fig. 4.
3. Fix the bracket to the solid section of the gate leaf.
