• The replacement of battery modules must be performed by authorised service techni-
cians only. When replacing batteries, replace with the same type and number of batter-
ies or battery modules.
2.4 Voltage inside the storage system
The storage system contains live electrical parts, which poses a risk of electrical shock.
Therefore:
„
Do not open the storage system.
2.5 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 mechan-
ical 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 extin-
guishing a fire in the storage system).
„
Do not heat the battery modules. Operate them only within the permissible temperat-
ure 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.
2.6 Conduct in case of a fire
Fire may occur with electrical equipment despite its careful design. Likewise, a fire in the
vicinity of the equipment can cause the storage system to catch fire, releasing the con-
tents of the battery modules.
In the event of a fire in the vicinity of the product or in the storage system itself, proceed
as follows:
