• The strings must have the same number of cells and
temperature.
Under these conditions a parallel connection of up to 4
strings is possible. The discharge data refer to the end poles
of each string.
The lead battery type can also vary as long as the required
charging voltage (V/cell) per string is fulfilled.
First pre-assemble each string individually. Make sure that
the strings have approximately the same charge state, i.e.
similar open-circuit voltages. Only then should the strings
be connected in parallel.

4.4 Operation
SAFETY INSTRUCTIONS WARNING!
RISK OF INJURY!
Improper installation can lead to serious personal injury and/
or damage to property. The battery may only be operated by
authorized and instructed personnel familiar with the operati-
on of the device and in compliance with all safety regulations.
Before starting work:
• Before starting work, check the battery for completeness
and technically perfect condition.
• Ensure sufficient freedom of movement.
ATTENTION!
Please do not stick over the battery valve covers when stik-
king on the battery block sensors or battery block numbering!
During operation:
• In case of malfunctions, first switch off the battery and
then secure it against switching on again.
Always wear when working on and with the battery:
• Safety shoes for protection against heavy falling parts and
slipping on non-slip surfaces.

4.5 Maintenance
SAFETY INSTRUCTIONS WARNING!
RISK OF INJURY!
Improper maintenance work can lead to serious personal
injury and/or damage to property. This work may only be
carried out by authorized and instructed personnel familiar
with the operation of the battery and in compliance with all
safety regulations.
MAINTENANCE ATTENTION!
Never use synthetic cloths or sponges to clean the blocks,
only water (damp cloths) without additives
4.6 General and controls
Regular checks and maintenance are necessary in relation to:
1. the specified charging voltages and currents,
2. the unloading conditions,
3. the temperature distributions,
4. the storage conditions,
5. the cleanliness of the battery and equipment,
6. and other conditions affecting the safety and service life of
the battery (e.g. ventilation of the battery compartment).
Sealed lead-acid batteries do not require refilling with water.
That is why they have been described as „maintenance-free" .
They are sealed by overpressure valves which cannot be ope-
ned without destruction. This is the reason for the definition
of Valve-Regulated Lead-Acid batteries.
Sealed batteries require the following checks:
Keep the battery clean to avoid leakage currents. Plastic parts
of the battery, especially the vessels, must be cleaned with
clear water without additives.
Measure and record at least every 6 months:
• Battery voltage
• Voltage of individual cells/blocks (approx. 20%)
• Surface temperature of individual blocks
• battery temperature
The optional battery monitoring system meets these
requirements automatically. See separate instruction
manual for battery block monitoring.
