3) Installation
!
The installation must be carried out by qualified personnel in compliance with current legislation, standards and regulations,
and the directions provided in this manual.

3.1) Preliminary checks

Before proceeding with the installation:
• Check that all the materials are in excellent condition, suitable for
use and compliant with current standards.
• Ensure that the structure of the gate is suitable for automation.
• Ensure that the mounting positions of the various devices are pro-
tected from impact and that the mounting surfaces are sufficiently
sturdy.
• Install cable or pipe leads only at the bottom of the unit; for no rea-
son whatsoever must the side and top walls be perforated. The
cables must only enter the unit from the bottom!
• Components must never be immersed in water or other liquids.
• Keep away from heat sources and open flames; in acid, saline or
potentially explosive atmosphere; this could damage A6 – A6F –
A700F and cause malfunctions or hazardous situations.

3.2) Fixing the control unit

Insert the two screws in the upper holes provided, sliding them on the guide as in fig. 3a and partly screwing them in. Turn the control unit
through 180° and perform the same operation with the other 2 screws. Fix the control unit on to the wall.
Fix the cover on the desiderd part (with opening on the right or left), press firmly on the arrows.
To remove the cover, press with a screwdriver on the join and push upwards at the same time.

3.3) Diagram of the connections

Once the unit, the actuators, the control (key selector or push button panel) and safety (emergency stop, photoelectric cells, sensitive edges
and flashing light) elements have been installed, you can now do the wiring, following the instructions given below.
!
To safeguard the operator and avoid damaging the components while you are wiring, whether it is low voltage (230 -120Vac) or extra low
voltage (24 V) or if you are plugging in the various cards:
The unit must, under no circumstances, be electrically powered.
We also wish to remind you that if the inputs of the NC (Normally Closed) contacts are not used they should be jumpered; if there is more
than one then they should be placed in SERIES with one another; if the inputs of the NO (Normally Open) contacts are not used they should
be left free and if there is more than one then they should be placed in PARALLEL with one another. The contacts must be of the mechani-
cal type and free from any potential; no connections are allowed like those defined as "PNP", "NPN", "Open Collector" etc., etc.
Carry out the necessary connections, following the diagram in Fig. 4 and the following description of the connections.
!
Remember that there are specific standards that must be complied with both as regards the safety of the electrical systems and as
regards automatic gates

• If there is an access door in the leaf, or within the range of move-
ment of the gate, make sure that it does not obstruct normal trav-
el. Mount a suitable interlock system if necessary.
• Only connect the control unit to a power supply line equipped with
a safety grounding system.
• The power supply line must be protected by suitable magne-
tothermal and differential switches.
• A disconnection device must be inserted in the power supply line
from the electrical mains (the distance between the contacts must
be at least 3.5 mm with an overvoltage category of III) or equiva-
lent system, for example an outlet and relative plug. If the discon-
nection device for the power supply is not mounted near the
automation, it must have a locking system to prevent unintention-
al, unauthorised connection.
