electrically isolate it.
Therefore:
►
Switch off the storage system to electrically isolate it (see 8.2 – p. 62).
Only then can the storage system be opened.
2.6 Handling the battery modules
The battery modules installed in the storage system are protected by multiple
protective devices and can be operated safely.
Despite their careful design, the battery cells inside the battery modules may
corrode or experience thermal runaway in the event of mechanical damage, heat or
a fault.
This can have the following effects:
•
High heat generation on the surface of the battery cells.
•
Electrolyte may escape.
•
The escaping electrolyte may ignite and cause an explosive flame.
•
The smoke from burning battery modules can irritate the skin, eyes and throat.
Therefore, proceed as follows:
►
Do not open the battery modules.
►
Do not mechanically damage the battery modules (pierce, deform, strip down,
etc.)
►
Do not modify the battery modules.
►
Do not allow the battery modules to come into contact with water (except
when extinguishing a fire in the storage system).
►
Do not heat the battery modules. Operate them only within the permissible
temperature range.
►
Keep the battery modules well away from sources of ignition.
►
Do not short-circuit the battery modules. Do not allow them to come into
contact with metal.
►
Do not continue to use the battery modules after a short circuit.
►
Do not deep-discharge the battery modules.
In the event that module contents are released:
►
Do not enter the room under any circumstance.
►
Avoid contact with the escaping electrolyte.
►
Contact the fire services.
