2.0 SYSTEM ELECTRICAL CONNECTION
- When making the electrical connections,carefully follow the
instructions for each of the components, referring to the wiring
diagram B1.
!
Warning
• Make the electrical connection of the single components after
having completed their installation.
• The entire circuit must be made consistent with the current
safety regulations.
• Use cables with a cross-section of 1.5 mm 2 for the wiring.
• Protect the operator power cable with a sheath if necessary;
do this before connecting the cable to the junction boxes.

3. INSTALLING THE OPERATOR
3.0 POSITIONING THE MOUNTINGS
The following table (C1) indicates the recommended data for defining
the position of the operator mountings in relation to the centre of
rotation of the gate leaf.
The distances A and B will give:
• The useful stroke length (C) of the piston
• The peripheral velocity of the gate leaf
• The angle of maximum opening of the gate leaf
• The holding capacity of the lock in relation to distance E (which must
always be less than B when the operator is fitted with a hydraulic
lock); the distance E is obtained, in practice, by measuring the
distance between front mounting fulcrum and gate hinge axis (see
fig. C1).
Caution
• The sum A+B corresponds to the useful stroke length of the
piston (C) for a 90° opening of the gate leaf.

!
• Every operator comes complete with a pickup capacitor. During
installation, connect the capacitor to the electrical equipment
according to the wiring diagram supplied.
- After making the electrical connections, check the thrust force at the
end of the gate leaf; if necessary, adjust the pressure of the operator
according to the procedure described in the specific paragraph.

• The minimum value of distances A and B is 70 mm; the
maximum one is indicated in column B of the table (see fig.
C1).
• Distances A and B must be as equal as possible in order to
have a uniform peripheral velocity.
• If the gate leaf shall be opened by more than 90°, first of all
find the best A and B measurements for mounting, then reduce
distance B to the desired opening angle, making sure, by
checking the distance Y, that the corner of the post does not
interfere with the operator action.
!
• The greater the distance B in relation to E, the more efficient
the holding capacity of the hydraulic lock (for all types of
operator).
• If the gate leaf is closed with an electric lock, then E must
always be less than or equal to B (never greater).
