WARNING: BEFORE USING THE BATTERY CHARGER
READ THE INSTRUCTION MANUAL CAREFULLY.
1. GENERAL SAFETY RULES FOR THE USE
- Avoid contact with battery acid. Should an operator
be sprayed or come into contact with the acid, rinse
the relative parts immediately under clean running
water. Continue to rinse the area until the physician
arrives.
- 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.
- Protect the eyes. Always wear protective goggles
when using acid lead accumulators.
- Always wear suitable clothing. Never wear baggy
clothing or jewellery that can get caught up in
moving parts. During all operations, electrically
insulated protection clothing and non-slip boots
must be worn at all times. Persons with long hair
must tie it back and wear a hair net.
- 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.
- In models without this element, connect plugs
of appropriate capacity, not below the fuse value
indicated on the rating plate.
- Class A device:
This battery charger complies with the requirements
of the technical standard for products to be used
in industrial environments and for professional
purposes. No compliance with the electromagnetic
compatibility in domestic use buildings is guaranteed
and those connected directly to a low voltage power
supply network that furnishes buildings designated to
domestic use.
2. GENERAL DESCRIPTION
Battery charger indicated for charging WET, GEL, AGM,
PbCa lead batteries used by motorised vehicles (petrol and
diesel) and electric vehicles: automobiles, motor vehicles,
motorcycles, boats, etc. It is possible to charge 6V, 12V and
24V batteries; the 50 model also has a starter aid mode (for
vehicles with petrol and diesel engines only).
Rechargeable batteries according to the output voltage
available: 6V / 3 cells; 12V / 6 cells; 24V / 12 cells.
3. INSTALLATION
3.1 BATTERY CHARGER POSITION
When running, position the battery charger in a stable
position and make sure the air flow through the openings
which guarantee required ventilation is not blocked.
3.2 CONNECTION TO THE MAINS
- The battery charger must only be connected to a power
supply system with neutral conductor connected to
earth.
- Check that the mains voltage is the same as the battery
charger voltage indicated on the rating plate.
- The power line must have a protection system, such as
fuses or circuit breakers, that can support the maximum
apparatus absorption.
- Use the relative power cable when connecting to the
mains.
- Any power cable extensions must be of suitable section
size, never lower than that of the supplied power cable.
- It is always compulsory to connect the device to the
grounding system, using the yellow-green wire in the
power cable identified with the label ( ), whilst the other
two wires must be connected to the phase and neutral
conductors on the mains power supply.
4. OPERATING DURING CHARGING
N.B.: Before charging, make sure the capacity (Ah)
of the battery to be charged is not lower than that
indicated on the battery charger rating plate (Cmin).
Follow the instructions scrupulously in the order given
below.
4.1 BATTERY PREPARATION
If the battery to be charged is the WET type, the procedure
is as follows:
- Remove the battery caps (if present), so that the gas
produced during charging can exit. Make sure the level
of electrolyte covers the battery plates; if they are not
covered, add distilled water until they are submerged by
5-10 mm.
