3 - PRELIMINARY CHECKS
Before installing the product, perform the following checks and in-
spections:
check that the gate, the door or the barrier is suitable for automation;
the weight and size of the gate or door and the balance of the barrier
boom must be within the operating limits specied for the automa-
tion system in which the product is installed;
check that the gate or door has rm, eective mechanical safety
stops;
make sure that the product xing zone is not subject to ooding;
high acidity or salinity or nearby heat sources might cause the pro-
duct to malfunction;
in case of extreme weather conditions (e.g. snow, ice, wide tempe-
rature variations or high temperatures), friction may increase, cau-
sing a corresponding rise in the force needed to operate the system;
the starting torque may therefore exceed that required in normal
conditions;
check that when operated by hand the gate, the door or the barrier
moves smoothly without any areas of greater friction or derailment
risk;
check that the gate, door or the barrier is well balanced and will the-
refore remain stationery when released in any position;
check that the electricity supply line to which the product is to be
connected is suitably earthed and protected by an overload and dif-
ferential safety breaker device;
the system power supply line must include a circuit breaker device
with a contact gap allowing complete disconnection in the condi-
tions specied by class III overvoltage;
ensure that all the material used for installation complies with the
relevant regulatory standards.
2.4 - List of cables required
• Electronic protection against short circuit and overload on the
FLASH, IND/ELEC and LED outputs
• Protection of 24VAC and PH-POW outputs via resettable fuses
• Automatic obstacle detection
• Auto-learning of travel length
• Disabling of unused safety inputs via dip switches: it is not
necessary to insert jumpers on the respective input terminals
(paragraph 4.2)

The following table shows the cables necessary for connection of
the various devices in a typical system.
The cables must be suitable for the type of installation; for example,
we recommend a cable type H03VV-F for installation indoors or
H05RN-F/H07RN-F if installed outdoors.
