Thank you for choosing a SERAI ELETTRONICA product, which we are confident will perform to your requirements.
Please be advised that you are about to fit a system classified as “a power-operated drive designed to move automatic ga-
tes and doors in commercial or residential buildings accessed by vehicles and persons”, and as such, the system must be
considered potentially hazardous. By law, you are responsible for rendering this equipment as “safe” as is reasonably pos-
sible.
Installation and maintenance of equipment of this kind must therefore be carried out by skilled, qualified and trained
personnel, working in a professional manner, as provided for by law n. 46/90 and any subsequent amendments and
supplements. The law in question prohibits the construction of these types of systems by non-qualified personnel.
SERAI manufacturing complies with the following legislation:
Applicable directives for the CE marking :
Machines: 98/37/EEC
Low Voltage: 73/23/EEC
Electromagnetic Compatibility: 89/336/EEC
General applicable standards:
Electrical Safety: IEC EN60335-1 + IEC EN60335-2-103
Electromagnetic Compatibility - Emissions: CEI EN61000-6-3
Electromagnetic Compatibility - Immunity: CEI EN61000-6-
Apart from the legislation mentioned above, you are also reminded to comply with the following standards during the
installation phase.
General applicable standards:
Safety of electrical systems in non-specialised environments: CEI 64-8
Specific product standards applicable:
Safety in the use of power-operated doors - requirements: UNI EN12453
Safety in the use of power-operated doors - testing methods: UNI EN12445
SERAI products enable users to build systems which comply with these standards. This is extremely important as THE
INSTALLER IS LIABLE FOR THE SYSTEM AND FOR ENSURING ITS OPERATION COMPLIES WITH LEGAL
PROVISIONS.
This handbook must be read in full before proceeding with the installation of the various parts of thesystem.
The installation of the mechanical end stops for gate opening and closure is necessary for system safety purposes
and therefore this operation must be performed before proceeding with the installation of the control unit.
ATTENTION: The IP66 protection degree -protection against powerful water jets- is guaranteed with rainfall
and perfectly functioning drain. On installations at the side of asphalt roads, where the waters are acid due
to the washing away, the external parts of the motor can be corroded and, in time, generate water
infiltrations. For this reason perfectly functioning drains are very important so that the water -especially if
acid- remains the least possible time in contact with the motor.

STANDARD INSTALLATION
Advice for wiring up in non-specialised environments.
1. Fit an omnipolar switch upstream of the system, choosing one with a gap of at least 3mm between the contacts. Or,
alternatively, use a 10Athermal magnetic circuit breaker.
2. Always make connections, of any type, with the system disconnected from the power supply, i.e. with the main switch
set to OFF (symbol “0”). The control unit, in particular, must never be connected to the power supply either during the
wiring up, or when fitting any expansion boards.
3. The following cables must be used for installation of the system:
22
- for the control unit, motor and electric lock power supplies: 1.5mm section for lengths of up to 19m, 2.5mm section
for lengths of up to 31m,
22
- for the flashing light: 0.75mm section for lengths of up to 3m, 1.5mm section for lengths of up to 19m,
- for the low voltage and current lines, (e.g. for the photocells, control buttons, electromechanical key, sensitive
22
edges and other safety devices: 0.5mm section for lengths of up to 50m, 0.75mm section for lengths of up to 100m.
4. Wire up the earth connection in compliance with legal provisions.

The installation of mechanical stop-blocks for opening and closing phase is necessary to
guarantee system security and therefore it is compulsory to install them, before installing the
control panel.

3-Take the motor out of the metal botton box.
ATTENTION
The motor is fixed on the foundation box by means of two normal nuts, due to problems of
transport. To install the motor in the system, these two nuts have to be removed and trown away,
replaced with four self-locking nuts as standard
4-Arrange the founding box at ground level and check the horizontal level and the perfect vertical alignment of the upper
hinge with the foundation box pin. Check that the distance between the pillar and the centre of the pin is higher than 65
mm.
The lower hinge -if present- must be removed.
5-The lower hinge -if present- must be removed.
6-Pre-arrange piping for the draining of the rainfall.
7-Cement definitively with concrete.
The connection between the power supply cable of the motor and the cable of the control panel
has to be carried out outside the foundation box and inside a weather proof housing. On the
contrary a water infiltration may be occur through the power supply cable causing the motor
failure.

The considerable differences in
temperature between summer
and winter can cause differing
rates of expansion in all
materials, including those used
in the building of our motors.
That is why we recommend you
check the impact force setting at
the start of winter and summer.
MOTOR FORCE ADJUSTMENT
The SERAI CR/41 control unit allows:
A- adjustment of the motors strength by acting on the "Power" potentiometer in the control unit
B- programming of the slowing which prolongs the life of the motor avoiding the gate banging against the
mechanical stops
If slowing has been inserted, the motor has less strength and therefore the gate, if not well-done,
may stop before having completed the manoeuvre.
By excluding the slowing the gate bangs against the mechanical stops causing a, more or less,
loud noise, according to installation. Also, the internal gears are subject to greater stresses.
