Figure 4:
First connect the red charging cable to the positive
pole of the battery.
Figure 5:
Finally, the black charging cable is connected to the
bodywork.
Figure 6:
After the battery has been connected to the charger,
you can connect the charger to a socket supplying
230V~50Hz. Do not connect it to a socket that
supplies any other mains voltage.
Important. Charging may create dangerous
explosive gas and therefore you should avoid spark
formation and naked flames whilst the battery is
charging. There is a risk of explosion!
Turn on the equipment using the ON/OFF switch (Fig.
1/Item 3).
Figure 7:
Calculating the charging time
The charging time depends on the charge status of
the battery. If the battery is fully discharged, the
approximate charging time can be calculated using
the following formula:
Battery capacity in Ah
Charging time/h =
Amp. (arit. charging current)
24 Ah
Example = = 9,6 h max.
2,5 A
A high initial current, approximately equal to the
rated current will flow in a normally discharged
battery. As the charging time increases, the charging
current will fall.
Old batteries for which the charging current does not
fall are suffering from a defect, such as a cell short
circuit or ageing damage.
Figure 8:
A high charge can only be identified by measuring
the acid density using an acid tester. Note! Gases
are released during the charging process (bubbles
will form on the surface of the battery fluid). It is
essential that you ventilate the rooms well.
Acid density values (kg/l at 20°C)
1.28 Battery charged
1.21 Battery semi-charged
1.16 Battery discharged
Figure 9:
Turn off the equipment using the ON/OFF switch (Fig.
1/Item 3).
Pull the plug out of the socket.
Figure 10:
First disconnect the black charging cable from the
bodywork.
Figure 11:
Then release the red charging cable from the
positive pole on the battery.
Figure 12:
Screw or push the battery stoppers back into position
(if there are any).
6. Overload cut-out
Figure 13:
The integral flat fuse on the underside of the
equipment protects the device from polarity reversal
and short circuits. If the fuse suffers a defect it must
be replaced by a new fuse with the same amp value.
If you wish to replace the flat fuse, first pull the mains
plug out of the socket and remove the charger
clamps from the battery. In the event of a thermal
overload, an automatic circuit breaker will stop the
charging process. After a cooling break it will cut in
again automatically.
7. Maintenance and care of the battery
Ensure that your battery is always fitted securely.
A perfect connection to the cable network of the
electrical system must be ensured at all times.
Keep the battery clean and dry. Apply a thin
coating of grease to the connection terminals
using an acid-free, acid-resistant grease
(Vaseline).
Check the level of the acid in batteries that are
not maintenance-free versions approximately
every 4 weeks and top up with distilled water if
necessary.
