stand the resulting risks of doing so. Children must not play with the device.
Cleaning and user maintenance must not be carried out by children without su-
pervision.
2.4 Product modifications or changes to the product
environment
• Only use the storage system in its original state - without any unauthorised
modifications - and when it is in proper working order.
• Safety devices must never be overridden, blocker or tampered with.
• The interfaces of the storage system must be wired in accordance with the
product documentation.
• An appropriate and readily accessible disconnect device shall be incorporated
in the fixed wiring.
• All repairs on the storage system must be performed by authorised service
technicians only.
• The replacement of battery modules must be performed by authorised service
technicians only. When replacing batteries, replace with the same type and
number of batteries or battery modules.
2.5 Voltage inside the storage system
5 min
The storage system contains live electrical parts, which poses a risk of electrical
shock. The storage system inverter also contains capacitors which carry voltage
even after the storage system is switched off. Therefore:
„
Switch off the storage system to electrically isolate it (see Switching the stor-
age system off to electrically isolate it [P. 54]).
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 run-
away 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.
