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.
- Make sure the power outlet is protected by an earth
connection.
- For models supplied without plugs, connect plugs having
a capacitance suitable for the value of the fuse shown in
the plate; for models supplied with cable and plug and with
a "P.MAX START" power higher than 9kW, when used for
starting, we advise replacing the plug with one having a
capacitance suitable for the fuse shown in the plate.
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.
- Accumulators rechargeable in accordance 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.
- The charger case has a protection degree of IP 20 and is
protected against indirect contacts by an earth lead as
required for class I equipment.
3. INSTALLATION
ASSEMBLY (FIG.A)
- Unpack the battery charger and assemble the separate
parts contained in the package.
- Models on wheels are to be set in a vertical position.
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 THE MAIN SUPPLY
- The battery charger should be connected only and
exclusively to a power source with the neutral lead
connected to earth.
Check that the mains voltage is the same as the voltage of
the equipment.
- Check that the power supply is protected by systems such
as fuses or automatic switches, sufficient to support the
maximum absorption of the equipment.
- The connection to the main supply has to be made using a
suitable cable.
- If you put an extension to the primary cable, the section
should be adequate and, in any case, never less than that
of the cable supplied.
- You always have to earth the equipment with the
yellow/green wire contained in the main cable, indicated
by the label ( W
connected to the mains.
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.
- Please remember that the exact charge status of the
battery can only be determined by using a densimeter
which allows measurement of the specific gravity of the
electrolyte the following indicate approximate density
values for the solute (Kg/l at 20°c):
1.28 = charged battery
1.21 = half-charged battery
1.14 = flat battery
- With the power supply cable disconnected from the main
power supply outlet, position the 6/12 V or 12/24 V switch
(if present) according to the rated voltage of the battery to
be charged.
- Position the switch/es for adjusting the type of charge (if
present) as required (FIG.B. LOW normal charging,
HIGH rapid charging).
- 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).
