Preliminary checks
Before proceeding with the installation of Dynamos you must:
• Check that all the materials are in excellent condition, suitable for
use and that they conform to the standards currently in force.
• Make sure that the structure of the gate is suitable for automation.
• Make sure that the weight and dimensions of the gate fall within the
specified operating limits provided in chapter 3.1 - Operating limits.
• Check, by comparison with chapter 5 - Technical characteristics,
that the force required to start the movement of the gate is less than
half the "maximum torque", and that the force required to keep the
gate in movement is less than half the "nominal torque". The manu-
facturer recommends a 50% margin on the force, as unfavourable
climatic conditions may cause an increase in friction.
• Make sure that there are no points of greater friction in the opening
or closing travel of the gate leaves.
• Make sure there is no danger of the gate derailing.
• Make sure that the mechanical stops are sturdy enough and that
there is no risk of the deformation even when the leaf hits the me-
chanical stop violently.
• Make sure that the gate is well balanced: it must not move by itself
when it is placed in any position.
• Make sure that the area where the gearmotor is fixed is not sub-
ject to flooding. If necessary, mount the gearmotor raised from the
ground.
• Make sure that the installation area enables the release of the gear-
motor and that it is safe and easy to release it.
• Make sure that the mounting positions of the various devices are
protected from impacts and that the mounting surfaces are suffi-
ciently sturdy.
• Components must never be immersed in water or other liquids.
• Keep Dynamos away from heat sources and open flames and
acid, saline or potentially explosive atmosphere; these may damage
RUN and cause malfunctions or dangerous situations.

• If there is an access door in the gate, or within its range of move-
ment, make sure that it does not obstruct normal travel. Mount a
suitable interlock system if necessary.
• Connect the control unit to an electricity supply with a safety earth
system.
• The power line must be protected by suitable thermal cutouts and
differential circuit breakers.
• The mains line must also be equipped with a power disconnect
device (with overvoltage category III, i.e. minimum gap between con-
tacts of 3.5 mm) or an equivalent system such as socket with remov-
able plug. If the power disconnection device is not in the vicinity of
the automation, it must be lockable against unintentional and unau-
thorised reconnection.
