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 specified for the automa-
tion system in which the product is installed;
heck that the gate or door has firm, effective mechanical safety
stops;
make sure that the product fixing zone is not subject to flooding;
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;
can be used as an alternative
- Safety device deactivation by means of dip switches: there is no
need to bridge the terminals of safety devices which are not instal-
led - the function is simply disabled by means of a dip switch.

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;
he system power supply line must include a circuit breaker device
with a contact gap allowing complete disconnection in the condi-
tions specified by class III overvoltage;
ensure that all the material used for installation complies with the
relevant regulatory standards.
