INSTRUCTION MANUAL
WARNING: BEFORE USING THE BATTERY CHARGER
READ THE INSTRUCTION MANUAL CAREFULLY.
1. GENERAL SAFETY RULES WHEN USING THIS
BATTERY CHARGER
- During the charge the battery produces explosive gases,
avoid the formation of flames and sparkes. 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.
- People (children included) whose physical, sensory or
mental capacities would prevent them from using the
appliance correctly must be supervised by a person
who is responsible for their safety while the appliance
is in use.
- Children must be supervised to ensure that they do
not play with the appliance.
- Use the battery charger only indoors and make sure that
you start it in airy places. DO NOT SET IN THE 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 use the battery charger inside the car or in the
bonnet.
- Substitute 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 or in a similar place set the
battery charger in a suitable case.
- Repair or maintenance of the inside of the battery charger
can be executed only by skilled technicians.
- WARNING: ALWAYS DISCONNECT THE POWER
SUPPLY CABLE FROM THE MAINS BEFORE
CARRYING OUT ANY SIMPLE MAINTENANCE
OPERATION ON THE BATTERY CHARGER.
2. I N T R O D U C T I O N
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. and is suitable for
charging sealed batteries.
- 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.

RED LED - Polarity inverted. Danger!!!
A N D G E N E R A L
YELLOW LED - Charging in progress.
GREEN LED - End of charging.
GREEN LED - Correct power supply.
4. 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 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.

5. 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).
CHARGE
- Power the battery charger by inserting the power supply
cable into the power outlet and turning the switch (if
present) to ON.
During this phase the battery charger will constantly
monitor the voltage at the ends of the battery,
automatically delivering or cutting off when necessary the
battery charging current. The set of leds on the equipment
will display the battery loading status.
END OF CHARGE
- Remove the power supply from the battery charger by
turning the switch to OFF (if present) and/or removing the
power supply 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).
