2.4 - list of cables needed
Typical installation cables required for connection of various devices
are shown in 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 specifi ed for the automation system in which the product is
installed;
check that the gate or door has fi rm, effective mechanical safety
stops;
make sure that the product fi xing zone is not subject to fl 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 specifi 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 installation; for example,
we recommend a H03VV-F type cable for indoor installation and
H07RN-F for outdoor.
2.4 - list of cables needed
- Power supply protected against short circuits within the unit, on
motor and connected accessories.
- Power adjustment with chopping of the current.
- Detection of obstacles by monitoring the encoder from the motor.
- Automatic learning of the working time.
- Disabling of safety inputs via dip switches: no need to bridge the
terminals related to the safety not installed, by simply disabling the
function with the dip switch.
- Ability to operate with an optional battery without power supply.
- Low voltage output used for a status indicator light or a 24V fl ash-
ing light.
- Energy savings function.
