Operation - Telwin Nevaboost 140 Instruction Manual

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.

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.
- The charging current delivered by the battery
decreases according to the characteristic W bend - see
the DIN 41774 norm.
3. INSTALLATION
POSITIONING THE BA TTERY 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.

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 ELECTROL YTE 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 batter y 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. PROTECTION (FIG. B)
The battery charger is equipped with protection in case of:
- 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.
