2. INSTALLATION
2.1. ELECTRIC PREPARATIONS (STANDARD SYSTEM )
To lay cables, use adequate rigid and/or flexible tubes.
To avoid any type of interference, we advise you to always separate
the 230 Vac power cables from the low voltage command cables,
using separate sheaths.
If it is necessary to extend the motor power cable, use a cable
suitable for outdoor mobile laying.

2.2. PRELIMINARY CHECKS

To ensure a correctly operating automated system, the structure
of the existing gate or gate to be built must satisfy the following
requirements:
• The construction elements of the gate must comply with the
provisions of the EN12604 and EN 12605 standards.
• Leaf dimensions must not exceed the values indicated in pa-
ragraph 1.1.
• The travel limit mechanical stops, for both opening and closing,
must be installed.
• The structure of the leaves must be sufficiently rigid and sturdy,
suitable for the automated system.
• Leaf movement must be smooth and free of any jamming during
the entire travel.
• Adequately sturdy hinges, in good condition
• Check the possibility of fastening the operator, respecting the
installation dimensions – see paragraph 2.3.
• Check if an efficient earth plate is present for electrical connec-
tion to the operator.
Do not use the operator to move safety exits or gates installed
on emergency routes (see escape routes).
If a pedestrians door is built into the leaf due to be motorised,
you must add a safety switch on the door, connected to the
stop input, in order to prevent the automated system working
while the door is open.
The condition of the gate structure directly influences the safety
and reliability of the automated system.
We advise you to carry out the metalwork jobs if any, before
installing the operator.

2.3. INSTALLATION DIMENSIONS

Determine the installation position of the operator by referring to
figure 4, where the minimum off-
ground height is specified.
To determine the operator instal-
lation dimensions, consult figure 5
and the relevant table.

eneral rules for determininG the installation dimensions
1. To obtain 90° opening of the leaf: A+B=C.
2. To obtain leaf opening greater than 90°: A+B<C.
3. Lower dimensions A and B cause greater leaf peripheral
speed.
4. Limit the difference between dimension A and dimension B
within 4 centimetres; higher differences cause considerable
leaf peripheral speed variations during closing and opening
movements.
5. Maintain a Z dimension ensuring that the operator does not
impact the pilaster, while the leaf is closed.
If the dimensions of the pilaster or the position of the hinge do not
allow the operator to be installed,
to respect the determined
dimension A, a niche must be
created on the pilaster as shown
in figure 6. The dimensions of the
