Introduction
Thank you for purchasing this quality product. To minimise the risk of injury we urge that our clients
take some basic safety precautions when using this device. Please read the operation instruc-
tions carefully and make sure you have understood its content.
Keep these operation instructions safe.
Safety instructions
Caution!
When using the appliance, some safety precautions must be observed to avoid injury and damage.
Read the operating instructions and the safety instructions completely and carefully. Keep these instruc-
tions in a place where you can access them at any time. If you pass the appliance on to someone else,
pass on these operating instructions and the safety regulations as well. We accept no liability for damage
or accidents caused by failure to follow these instructions and the safety instructions.
•The series battery chargers are designed for charging lead-acid batteries, gel batteries and
AGM batteries. They cannot be used as a DC power source or for any other purpose to
prevent accidents such as fire and electric shock.
•The charger is only designed for a suitable power outlet. If the power cable needs to be
extended, ensure that the extension cable is of sufficient size to supply power over the re-
quired distance.
•If the charger is interrupted while charging or other damage is caused by exposure to a violent
impact, discontinue use immediately.
•The charger must not be disassembled. If repairs are necessary, they must be carried out by
a qualified electrician. Improper reassembly may result in a fire hazard and/or electric shock.
•Disconnect the charger from all connected batteries and from the mains before cleaning the
housing.
•Disconnect the charger from the mains after charging is complete. Then remove the battery
connector.
•Warning! Explosive gases are produced during charging; therefore, avoid sparks and naked
flames or smoking in the vicinity of the unit.
•Only charge the battery in ventilated rooms. It is strictly forbidden to use the unit in a vehicle
or under the closed bonnet.
•The battery charger cannot be used for non-rechargeable batteries.
•If the mains cable is damaged, it must be replaced by a qualified electrician to avoid a hazard.
•The battery terminal that is not connected to the vehicle must be connected first. The other
connection must be made on the vehicle, at a sufficient distance from the battery and the fuel
line. The battery charger must then be connected to the power supply.
•This appliance is not intended for use by persons (including children) with reduced physical,
sensory, or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not play with the appliance.
•Batteries store a large amount of energy. Be sure to avoid short-circuiting the battery or
charger terminals, otherwise the energy stored in the battery will be released immediately.
This may result in fire or injury.
•Do not allow children to play with the appliance.
•Cleaning and user maintenance must not be carried out by children without supervision.

Notes on automatic charging
The charger is a microprocessor-controlled automatic charger, i.e., it is particularly suitable for charging
maintenance-free batteries and for long-term and trickle charging of batteries that are not in constant
use, e.g., for vintage cars, motorhomes, lawn tractors and the like. The integrated microprocessor ena-
bles charging in several stages. The last charging step, the trickle charge, keeps the battery capacity at
95–100 % and thus the battery always fully charged. The charging process does not need to be moni-
tored. However, do not leave the battery unattended when charging it for a longer period so that you
can disconnect it from the mains in case of a malfunction of the charger.
Charging settings
Press the mode function button (fig. 1, 1) to set the charging functions 12 V/2 A (fig. 2, A), 12 V/4 A (fig. 2,
B) and 12 V/4 A winter mode (fig. 2, C).
Charging the battery
•Loosen or remove the battery plugs (if present) from the battery.
•Check the acid level in the battery. Top up with distilled water if necessary (if possible). Im-
portant! Battery acid is aggressive. Rinse off any acid splashes thoroughly with plenty of
water and consult a doctor if necessary.
•First connect the red charging cable to the positive terminal of the battery.
•Then connect the black charging cable to the body of the vehicle, not to the battery and fuel
line.
•Warning! Normally, the negative terminal of the battery is connected to the body and you
can pass to the next step. In exceptional cases, however, it is possible that the positive ter-
minal of the battery is connected to the body (positive earth). In this case, connect the black
charging cable to the negative terminal of the battery. Then connect the red charging cable
to a point that is a sufficient distance from the battery and the fuel line.
•After the battery has been connected to the charger, you can connect the charger to a 230 V
~ 50 Hz socket. The unit automatically detects the nominal voltage (6 V or 12 V) of the con-
nected battery. The LCD display lights up green. Do not connect the unit to a socket that
supplies a different mains voltage.
Important! Dangerous explosive gases may be produced during charging. Therefore, avoid
sparks and open flames during charging. There is a risk of explosion!
•If the battery terminals are connected the wrong way round, the interchange protection en-
sures that the battery and the charger are not damaged. In this case, disconnect the charger
from the battery and the socket. Wait about 3 min and then restart the charging process.

The charging time depends on the state of charge of the battery. If the battery is completely discharged,
the approximate charging time until the battery is approximately 80 % charged can be calculated using
the following formula:
Battery capacity (Ah) ÷ Charging time (h) = Charging current (A).
The charging current should be ⅒ to ⅙ of the battery capacity.
Note! Gases are released during the charging process. Make sure that the rooms are well ventilated.
As long as the unit is charging, the LCD display lights up green. When the battery has finished charging,
the LCD display lights up blue.
Stopping the charging of a battery
•Pull the plug out of the socket.
•First detach the black charging cable from the body.
•Then disconnect the red charging cable from the positive terminal of the battery.
•Important! In case of positive earth, first disconnect the red charging cable from the body
and then the black charging cable from the battery.
•Screw or slide the battery plugs (if present) back into place.
Testing 12 V batteries
Connect the charger to the battery. The LCD symbol “H” (fig. 2) indicates the state of charge (1 bar =
25 %). The battery voltage is shown on the LCD display.
Overload switch-off
The charger is equipped with electronic protection against overcharging, short circuit, and reversed
poles. In addition, one or more fine-wire fuses are fitted. If a fuse is defective, it must be replaced by a
new fuse with the same ampere rating. If necessary, contact a qualified electrician.
Battery maintenance and care
•Make sure that your battery is always securely fastened.
•A proper connection to the mains supply of the electrical system must be always ensured.
•Keep the battery clean and dry. Apply a thin layer of grease to the terminals with an acid-free
and acid-resistant grease (e.g., Vaseline).
•For batteries that are not maintenance-free, check the acid level about every 4 weeks and
top up with distilled water if necessary.
Danger! Always disconnect the mains plug before starting cleaning work.

Cleaning
•Keep all safety devices, ventilation openings, and the housing as free of dirt and dust as
possible. Wipe the unit with a clean cloth or blow it out with compressed air at low pressure.
•We recommend cleaning the unit immediately after each use.
•Clean the unit regularly with a damp cloth and a little soft soap. Do not use any cleaning
agents or solvents; these could attack the plastic parts of the unit. Make sure that no water
can penetrate the appliance. The ingress of water into a power tool increases the risk of
electric shock.
•The charger should be placed in a dry room for storage. Any corrosion must be removed from
the charging terminals.
Maintenance
There are no parts inside the unit that require additional maintenance.
Troubleshooting
If the unit is operating properly, you should not have any problems with malfunctions or errors. In case
of malfunctions or errors, please check the following before contacting a specialist:
