Description Of The Product - Nice Mindy A500 Instrucciones Y Advertencias Para El Instalador

1) Description of the product:

This unit controls an alternate current three-phase or single-phase
motor at 230V or 400V for automatic doors and gates. It features
obstacle detectors (anti-crush devices) and a braking system which
reduces inertia during the stopping phase. It also features a series of
functions that can be selected by dip-switches (mini-switches) and
adjustments performed by trimmers.

2) Installation:
Before starting to install the unit, check the sturdiness and
mechanical consistency of the gate and make sure safety stops and
minimum distances are respected. Carry out a careful and thorough
"risk analysis" of the automatic system, evaluate the safety devices to
be installed with particular care and always fit an emergency stop
device.
Make absolutely sure that the mechanical stops are of the right shape
and strong enough to stop the motor in all conditions; they must be
able to absorb all the kinetic energy accumulated during movement
without deforming in the slightest.
! Do not install the motor without the "Mechanical travel
stops"
Besides the standards referring to electrical installations in general,
automatic machines, doors and gates, we also supply some specific
notes that will make the whole system even safer and more reliable:
-The power line leading to the unit must always be protected by a
circuit breaker or three 5A-fuses; a differential switch is
recommended but not essential if there is already one up-line from
the system.
-Power the unit using a 5 x 1.5 mm
earth); should the distance between the unit and the earth
connection exceed 30 m, install an earth plate near the unit.
-Use wires with a minimum cross section of 0.25 mm
voltage safety circuits.
Use shielded wire if the length exceeds 30 m and connect the earth
braid only on the unit side.

-Only use cables (various individually insulated wires plus an
additional general insulation); never use single wires even if they are
protected inside ducts.
-It is absolutely forbidden to connect cables in buried boxes even if
they are completely watertight.
Make sure you have all the necessary materials suitable for this use.
The unit must be installed correctly in order to guarantee an adequate
level of safety and protection against atmospheric agents. Please
bear in mind that the unit contains particularly delicate live parts and
electronic components.
The unit is supplied in a container which, if appropriately installed, will
guarantee a protection level of IP55 (in compliance with CEI 70-1 and
IEC 529) which means it is also suitable for outdoor installation.
However, several simple but important rules must be followed:
-Install the unit on a permanent surface, perfectly flat and adequately
protected against knocks, making sure that the unit bottom is at least
40 cm from the ground.
-Install cable or pipe leads only at the bottom of the unit; for no
reason whatsoever must the side and top walls be perforated. The
cables must only enter the unit from the bottom!
