1. GENERAL SAFETY RULES FOR THE USE
- During the charge the battery produces explosive gases, avoid
the formation of ames 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 prevent damaging the vehicle electronics, scrupulously respect the
warnings given by the producer of the vehicle or the batteries used.
- 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.
- The battery charger is protected from indirect contact by an earth wire as
indicated for class I equipment. 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. GENERAL DESCRIPTION
2.1 TRADITIONAL BATTERY CHARGERS
Manual battery chargers (the operator must intervene to stop the charge
process) indicated for charging free electrolyte lead acid batteries (WET)
used in engine-driven vehicles (petrol and diesel), motorcycles, boats, etc.
6V, 12V and 24V batteries can be recharged according to the available
output voltage. Some models have the START or the BOOST&GO mode to
start engine-driven vehicles.
2.2 AUTOMATIC BATTERY CHARGERS (TRONIC)
Automatic battery chargers (electronic control of the charging process,
interruption and automatic reset) suitable for charging sealed batteries (GEL,
AGM) in the TRONIC mode, and free electrolyte lead acid batteries (WET) in
the manual CHARGE mode (see par. 2.1), used with engine-driven vehicles
(petrol and diesel), motorcycles, boats, etc. It is possible to recharge 12V and
24V batteries.
3. BOOST - BOOST&GO FUNCTIONS
These functions speed up charging and help vehicle starting thanks to fast
battery pre-charge (the charging time depends on the battery capacity
and discharge level). When using models with the BOOST&GO function,
vehicles can be started up with the cables still connected to the battery (see
paragraph 7). During the charging process, always follow the indications
given in paragraph 4.
4. AMMETER READING (FIG. A)
The ammeter allows reading the current supplied by the battery charger
to the battery (a completely at battery initially requires maximum current
which lowers over time). During the charging phase the ammeter indicator
moves from right to left, indicating a decrease in the current required by the
battery until very low levels (near to zero) are reached (fully charged battery),
at a speed and with an accuracy that depend on the capacity, battery state
and ammeter reading precision. Please remember that the exact charge
status of the battery can only be determined by using a densimeter which
allows measurement of the specic gravity of the electrolyte. With manual
battery chargers, the ammeter must be monitored to determine when
the battery has nished charging. Once the battery is charged it must be
disconnected to prevent overheating or damage.
5. INSTALLATION
5.1 ASSEMBLY (FIG. B)
Unpack the battery charger and assemble the separate parts contained in
the package. Models on wheels are to be set in a vertical position.
5.2 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 sucient ventilation.
5.3 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, sucient 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), while the other
two wires should be connected to the phase and the neutral cable.
6. OPERATION DURING 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 of the
battery charger (C min). Follow the instructions, taking great care to
respect the order given below.
6.1 BATTERY PREPARATION
When recharging a WET-type battery, proceed as follows:
- 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.
6.2 BATTERY CHARGER/BATTERY CONNECTION
- Make sure the power cable is disconnected from the mains.
