Labelling the Battery System
You have to attach visible polarity labels to the end terminals of the battery. It is
recommended to equip the FNC
®
cells with consecutive numbers (from the positive to the
negative terminal of the battery).
Battery systems with a nominal voltage
≥ 75 V installed in the EU must carry a CE
conformity marking. Contact HOPPECKE for further information.

DANGER!
Danger of explosion due to formation of oxyhydrogen gas!
When the cells are charged, water is decomposed and a hydrogen-oxygen-gas mixture
(oxyhydrogen gas) is formed, which already explodes with low energy input.
Keep any source ignition away from the battery system:
Open flames or fire
Smoking
Glowing embers
Flying sparks during grinding work
Electrical sparks caused by switches or fuses
Hot surfaces with temperature above 300°C
Electrostatic discharges
Work with electrically insulated tools that do not strike sparks. Ground yourself when working
directly on the battery system.
Make sure that there is adequate ventilation in the container room in accordance with DIN EN
IEC 62485-2, so that the potential explosive gas mixture is discharged.
