Calculation of the loading time
Fig. 3
The charging time depends on the state of charge of the battery. If the battery is completely dis-
charged, the approximate charging time until the battery is approximately 80% charged can be calcu-
lated using the following formula:
Battery capacity (Ah) ÷ Charging time (h) = Charging current (A).
The charging current should be
to of the battery capacity.

Notice!
Gases are released during the charging process. Make sure that the rooms are well ventil-
ated.
As long as the unit is charging, the LCD display lights up green. When the battery has finished char-
ging, 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.
