1 Safety regulations relating to the
operation of battery chargers
To ensure the safety of a battery charger,
the equipment (charger, cables, battery)
must be in good working order. Operation
must be in such a way that no danger is
posed to persons.
F
Check the insulation before using the
charging cables and connectors.
Faults and defects must be rectified
immediately by trained personnel
(see “Safety instructions to be observed
during servicing” on page 11).
The following items are taken from the legal
requirements and guidelines of German
and international associations and
organizations.
Ventilation:
Battery chargers must be set up so that
they are not exposed to charging gases and
electrolytic mist.
Chargers and batteries must therefore be
housed in separate locations wherever
possible. If this is not possible, adequate
natural and artificial ventilation must be
provided to ensure that the gas mixture
generated during charging will lose its
explosiveness.
Functional test:
When commissioning new charging
equipment, and thereafter at adequate
intervals, checks must be performed to
ensure correct operation of the battery
charger, and especially correct functioning
of automatic charging switches and
measurement instrument display.
At the start of charging, the amperage and
voltage must be checked in order to detect
any irregularities in the patterns of the
battery or charging equipment.
Mains supply:
If, in the event of mains voltage fluctuations
lasting over a long period of time, the output
voltage changes, the battery chargers must
be readjusted ensuring that the admissible
limits as indicated by the battery supplier
are observed (e.g. final charging current in
the case of lead batteries).
Z
Short-time mains voltage fluctuations may
be ignored.
Charger assignment:
The charging procedures, or charging
characteristics, as well as the charging
equipment must be adapted to the
operating conditions and technical data of
the batteries.
Battery charging:
The connector must only be disconnected
from the socket after the battery charger
has been switched off. The top of the
battery cells must be exposed during
recharging to ensure adequate ventilation.
Do not rest any metal objects on the
batteries.
Z
Note the battery manufacturer’s
regulations.
M
Do not exceed the temperature limits
stipulated by the battery supplier. This
applies also to any heating that may occur
as the battery is recharged.

3.6 Manual charging interruption
M
The battery charger must only be switched
off using the control key (3) if charging is to
be interrupted manually.
This procedure will avoid malfunctions and
the charging connector cannot be damaged
by sparking.
If charging has been interrupted with the
control key (3) it can be continued by
pressing the key (3) again provided the
battery has not been disconnected.
3.7 Boosting charge
- Start the charging operation by
connecting the battery requiring
recharging (mains connector switched
on).
- The yellow “Charging” LEDs (2) light up
when battery charging is in progress.
- When the battery is fully charged, the
green “Charging complete” LED (7)
lights up. The battery and charging cable
can be disconnected.
- If you wish to disconnect the battery from
the battery charger while it is “half-full”,
first press the control key
(3) (see
“Manual charging interruption” on
page 10).
3.8 Manual Compensation Charge
The battery charger has a “manual
compensation charge” function.
Z
Compensation charging should be carried
out regularly (1x a week) in order to
compensate the charge differences
between the individual cells. When the
compensation charge is complete, the
recharging time is increased on a single
occasion by 2 hours.
When you press the control key (3) for
10 sec., prior to connecting the battery, the
compensation charge function is activated
once for the following charging operation.
The “Equilising charge” LED (4) lights up.
If the battery is not connected within
2.5 min., the “Equilising charge” function is
deleted.
3.9 Automatic equilising charge function
If the battery charger remains connected to
the battery for more than 24 hours after
charging operation is completed
(weekend), the compensation charge is
carried out automatically for 2 hours.
The “Equilising charge” LED (4) lights up
when the automatic equilising charge
function is carried out.
Z
When applying a manual compensation
charge (see “Manual Compensation
Charge” on page
10), automatic
compensation charge will not be performed
for the following charging operation.
4 Charging state indicator
Z
If no battery is connected, the final charging
state of the last charging operation can be
viewed on the display.
Press down on the control key (3) for
a maximum of 2 seconds and then release
it. The final condition of the last charge is
displayed.
The display goes out either automatically or
by briefly pressing the control key (3).
