INSTRUCTION MANUAL
WARNING: BEFORE USING THE BATTERY CHARGER READ THE
INSTRUCTION MANUAL CAREFULLY.
1. GENERAL SAFETY RULES WHEN USING THIS BATTERY CHARGER
- When under charge the battery produces explosive gases. prevent the
formation of flames and sparks. DO NOT SMOKE.
- Position the batteries to be charged in a well-ventilated place.
- Inexperience and untrained people should be properly instructed
before using the appliance.
- This appliance can be used by children aged from 8 years and
above and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in
a safe way and understand the hazards involved.
- Children shall not play with the appliance.
- Cleaning and user maintenance shall not be made by children
without supervision.
- Use the battery charger only indoors and make sure that you operate it
in well-ventilated places. DO NOT EXPOSE IT TO RAIN OR SNOW.
- Disconnect the mains cable before connecting to or disconnecting the
charging cables from the battery.
- Do not connect or disconnect the clamps to or from the battery with
the battery charger operating.
- Never under any circumstances use the battery charger inside the car
or under the bonnet.
- Replace the mains cable only with an original one.
- Do not use the battery charger to charge batteries which are not
rechargeable.
- Make sure the available power supply voltage corresponds to that
shown on the battery charger rating plate.
- To avoid damaging the vehicle's electronics, read, keep and take very
careful note of the information supplied by the vehicle manufacturer,
when using the battery charger either for charging or starting; the
same applies to the instructions supplied by the battery manufacturer.
- This battery charger has components, such as switches and relays,
which can cause arcs or sparks. Therefore when using it in a garage,
workshop or similar place the battery charger in a suitable room or
case.
- Repair or maintenance of the inside of the battery charger can be
executed only by skilled technicians.
- DANGER! ALWAYS DISCONNECT THE POWER SUPPLY CABLE FROM
THE MAINS BEFORE CARRYING OUT ANY SIMPLE MAINTENANCE
OPERATION ON THE BATTERY CHARGER.
2. INTRODUCTION AND GENERAL DESCRIPTION
- This battery charger can be used to charge free electrolyte lead acid
batteries used on petrol and diesel engine vehicles, motor cycles, boats
etc. .
- Rechargeable batteries according to the output voltage available: 6V /
3 cells; 12V / 6 cells; 24V / 12 cells.
- The charging current delivered by the battery decreases according to
the characteristic W bend - see the DIN 41774 norm.
3. INSTALLATION
POSITIONING THE BATTERY CHARGER
- During operation, position the battery charger on a stable surface
and make sure that there is no obstruction to air passage through the
openings provided to ensure sufficient ventilation.
CONNECTION TO POWER
- The battery charger should be connected only and exclusively to a
power source with the neutral lead connected to earth.
Check that the net voltage is the same as the voltage of the equipment.
- Check that the power supply is protected by systems as fuses or
automatic switches, sufficient to support the maximum absorption of

(EN)

welding.
- If you put an extension to the primary cable, the diameter must be the
same, never inferior.
- The connection to the power has to be made using the cable.
4. OPERATION
BEFORE CHARGING
NB: Before charging check that the capacity of the battery (Ah) which
is to be charged, is not inferior to that reported on the data table.
(C min).
Follow the instructions, taking great care to respect the order given
below.
- Remove the caps of the battery charger (if foreseen) so as to let the gas
produced go out.
- Check that the level of the electrolyte covers the plates of the battery. If
these were not covered add distilled water and cover them up to 5 - 10
mm.
WARNING: USE THE MAXIMUM CAUTION DURING THIS
OPERATION AS THE ELECTROLYTE IS A HIGHLY CORROSIVE
ACID.
- With the power supply cable disconnected from the power outlet,
position the 6/12 V or 12/24 V charge switch (if present) according to
the rated voltage of the battery to be charged.
- Check the polarities of the battery terminals: positive for the + symbol
and negative for the - symbol.
NOTE: if the symbols are indistinguishable remember that the positive
terminal is the one not connected to the vehicle chassis.
- Connect the red charge clamp to the positive terminal of the battery ( +
symbol).
- Connect the black charge clamp to the vehicle chassis, at a safe
distance from the battery and the fuel pipe.
NOTE: if the battery is not installed in the vehicle, connect the clamp
directly to the negative terminal of the battery (- symbol).
CHARGING
- Power the battery charger by inserting the power supply cable into the
power outlet and turning the switch (if present) to ON.
- The ammeter (if present) will indicate the current (in Amps) delivered
towards the battery: during this phase the pointer of the ammeter
will decrease slowly to very low values according to the capacity and
condition of the battery.
NOTE: Once the battery is charged you may note the liquid inside
the battery starting to "boil". It is advisable to stop charging when this
phenomenon appears so as to prevent damage to the battery.
ATTENTION : BATTERIES HERMÉTIQUES.
En cas de nécessité de charger ce type de batterie, faire
preuve d'une extrême attention. Procéder lentement à
la charge en contrôlant constamment la tension aux bornes de la
batterie. Si la tension, mesurable au moyen d'un testeur courant,
atteint 14,4V pour les batteries à 12V (7,2V pour les batteries à 6V
et 28,8V pour les batteries à 24V), il est conseillé d'interrompre la
charge.
END OF CHARGE
- Disconnect the power supply to the battery charger by disconnecting
the cable from the mains outlet.
- Disconnect the black charge clamp from the chassis of the vehicle or
from the negative terminal of the battery (- symbol).
- Disconnect the red charge clamp from the positive terminal of the
battery (+ symbol).
- Store the battery charger in a dry place.
- Close up the battery cells with the appropriate plugs (if present).
5. BATTERY CHARGER PROTECTIONS (FIG. B)
The battery charger protects itself from:
- Overloads (too much current delivered towards the battery).
- Short circuit (charging clamps set in contact with one another).
- Polarity reversal of the battery.
- For battery chargers equipped with fuses, it is necessary, in case of
substitution of fuses, to use spares having the same nominal current
value as the fuse changed.
WARNING: If fuses with current values different from those
given were used damages to persons and things could be
caused. For the same reason do not substitute the fuse with
copper (or other materials) bridge.
The substitution of the fuses is to be done when the mains cable is
disconnected from the mains.
