2.4 - List of cables required
The cables required for connection of the various devices in a stan-
dard system are listed in the cables list table.
Before installing the product, perform the following checks and in-
spections:
check that the gate or door is suitable for automation;
the weight and size of the gate or door must be within the operating
limits specied for the automation system in which the product is
installed;
check that the gate or door has rm, effective 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 or door moves smoothly
without any areas of greater friction or derailment risk;
check that the gate or door is well balanced and will therefore re-
main 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 specied by class III overvoltage;
ensure that all the material used for installation complies with the
relevant regulatory standards.
The cables used must be suitable for the type of installation; for
example, an H03VV-F type cable is recommended for indoor appli-
cations, while H07RN-F is suitable for outdoor applications.
- Power supply with protection against short-circuits inside the con-
trol unit, on motors and on the connected accessories.
- Obstacle detection during travel at normal speed by means of cur-
rent sensor.
- Automatic learning of working times.
- 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.
