01. Measure value "C", then trace a straight horizontal line in chart
1 against the obtained valued. Select a point in the line, taking into
account the desired opening angle, suitable for the column. Trace
a vertical line starting from the point identified and obtain value A.

Before proceeding with the installation, make sure that value A allows
to fix the rear bracket, otherwise select another point on the chart.
Finally, to fix the bracket on the leaf, refer to the maximum dimensions
of the arm in figure 3. 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).
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).
02. At this point, mark on the leaf and on the wall the holes of the
brackets which will then be used to fix the two brackets.

03. Fix the rear bracket of the motor to the wall complying with the
120
dimensions seen previously (fig. 5).
