M
battery
manufacturer’s
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.
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).
Short-time mains voltage fluctuations may
be ignored.

Z
The VDE 0510 safety regulations must be
observed.
Internal electrolyte circulation:
Internal electrolyte stirring is automatically
switched on at the beginning of the
charging procedure. Electrolyte stirring
mixes the acid before the gassing phase.
Z
In the main charging phase, the battery’s
energy consumption increases so that the
recharging phase can be shortened.
The internal charging electronics detect via
the sensor that the pump is switched on
and
reduce
the
recharging
time.
This shortens the total charging time at the
same battery charge level.
The internal electrolye stirrer consists of the
following parts:
- An additional switch contact to switch on
the pump;
- A sensor to switch or adapt the charging
factor;
- A membrane pump with an air filter and
air pressure monitor. The pump delivers
a constant pressure of 100 mbar and
overcomes an acid level of ca. 80 cm in
the main charging phase;
- A connecting hose with an air plug
connection in the pilot contacts of the
charging connector.

It is forbidden to store food in the vicinity of
battery chargers.
Description of the device
During the main charging phase, batteries
without electrolyte circulation generate acid
layers. The charging factor is set according
to the charging device.
Choose the assembly location so that:
- There is sufficient ventilation.
- The flow of cooling air through the
charger is not restricted. It must not be
installed close to radiators or similar heat
sources.
- No flammable gases or dust mixtures
can penetrate inside the charger.
- The charger is placed only on a solid and
secure surface. The surface must not
consist of flammable material.
- The bottom of the charger is
approx. 0.5 m above the battery to be
charged.
