Safety In order to connect optional components, it may be necessary to open the housing. The
following warning notices must be obeyed:
WARNING!
Danger from electric shocks.
This can result in serious injury or death.
► The housing must never be opened by anyone other than a service technician trained
by the manufacturer.
► The device must be disconnected from the mains before starting any work with the
housing open.
► A suitable measuring instrument must be used to ensure that electrically charged com-
ponents (e.g. capacitors) are fully discharged.
► Use an easily legible and understandable warning sign to ensure that the device is not
reconnected to the mains supply before all the work has been completed.
WARNING!
Danger due to work that has been carried out improperly.
This can result in serious injury and damage to property.
► All work involved with connecting optional components must only be carried out by
qualified specialist technicians.
► If Installation Instructions or User Information is available for the optional component
concerned, all warning notices and instructions therein must be obeyed.
► In the case of all optional components with electrical connections, once the connection
work is complete, a safety inspection must be carried out in accordance with relevant
national and international standards and directives.
► Further details on safety inspections can be obtained from your authorised service cen-
tre.
► They will provide you with any documents you may require on request.
Electrolyte circu-
lation
NOTE!
Danger due to the ingress of electrolyte from the battery or due to operation without
any back pressure.
This may result in damage to the air pump.
► Always set up the charger at least 0.5 m (1 ft. 7.69 in.) above the battery to be charged.
► Always use an undamaged connecting hose provided specifically for this purpose to
connect the charger's compressed air outlet to the battery.
NOTE!
Danger due to non-observance of the permissible mains voltage tolerance.
This can cause malfunctions and damage.
► For the electrolyte circulation option, a restricted mains voltage tolerance of 207 V to
250 V, phase-phase: 360 V to 433 V, applies for the charger.
