2 Safety
2.3.2 Danger to life due to explosive and flammable materials
►
Do not use the storage system in potentially explosive environments.
2.3.3 About repairs on the storage system
All repairs on the storage system must be performed by certified service
technicians only.
2.3.4 Danger to life due to product modifications or changes to
the product environment
►
Never block or bypass the protective devices.
►
Never modify the protective devices.
►
Do not make changes to the storage system.
►
Do not make changes to the electrical and data supply lines.
2.3.5 Conduct in case of a fire / Important information for fire
services
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 contents of the battery modules.
►
Observe the warnings about the risk of injury/burns due to the escape of
electrolyte (see section 2.5 – pg. 9).
In the event of a fire in the vicinity of the product or in the storage system itself,
proceed as follows:
►
Only firefighters with appropriate protective equipment (safety gloves, safety
clothing, face guard, breathing protection) are permitted to enter the room where
the burning storage system is located.
There is a danger of electrocution when extinguishing fire while the storage system
is switched on. Therefore, before starting to extinguish the fire:
►
Switch off the storage system.
►
Switch off the mains fuses in the building.
If the storage system and/or mains fuses cannot be safely switched off:
►
Observe the minimum distances specified in DIN VDE 0132 for the
extinguishing agent used.
The storage system works with an output voltage of 400 V (AC) and is therefore
considered a low-voltage system.
►
A storage system fire can be extinguished using conventional extinguishing
agents.
►
Water is recommended as an extinguishing agent in order to cool the battery
modules and therefore prevent thermal runaway in battery modules which are still
intact.
