8 Safety property. This device can be used by children from the age of eight (8) years old and individuals with impaired physical, sensory or mental capabilities or individuals with limited knowledge and/or experience of working with the device, as long as they are supervised or have been trained to safely use the device and understand 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 supervision. The storage system must only be operated as described in the product documentation.. 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. An appropriate and readily accessible disconnect device shall be incorporated in the fixed wiring. Safety devices must never be overridden, blocked or tampered with. The interfaces of the storage system must be wired in accordance with the product documentation. All repairs on the storage system and 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.. Voltage inside the storage system The storage system contains live electrical parts, which poses a risk of electrical min shock.

Wait five minutes until the capacitors have discharged. Only then can the storage system be opened. 8 / 9

9 Safety. 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. Do not open the battery modules. 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..7 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 contents 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: 9 / 9

10 Safety 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 to electrically isolate it (see section 8. - p. ). 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 for the extinguishing agent used. The storage system works with an output voltage of 0 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. Information on the battery modules: The battery modules have a nominal voltage of. V (DC) and therefore fall into the range of protected extra-low voltage (under 0 V DC). The battery modules do not contain metallic lithium. 0 / 9
