2 IMPORTANT SAFETY INSTRUCTIONS
2 IMPORTANT SAFETY INSTRUCTIONS
Keep the manual for future reference.
This section contains safety information that must be observed at all times when working.
Danger to life due to electric shock when live components or cables of the inverter are touched
High voltages are present in the conductive components or cables of the inverter. Touching live parts and cables of
the inverter results in death or lethal injuries due to electric shock.
• Disconnect the product and battery from voltage sources and make sure it cannot be reconnected before
working on the device.
• Wear suitable personal protective equipment for all work on the product.
• Do not touch non-insulated parts or cables.
Danger to life due to electric shock in case of overvoltages and if surge protection is missing
Overvoltages (e. g. in the event of a flash of lightning) can be further conducted into the building and to other
connected devices in the same network via the network cables or other data cables if there is no surge protection.
Touching live parts and cables results in death or lethal injuries due to electric shock.
• Ensure that all devices in the same network and the battery are integrated into the existing surge protection.
• When laying the network cables or other data cables outdoors, it must be ensured that a suitable surge
protection device is provided at the transition point of the cable from the product or the battery outdoors to the
inside of a building.
• The Ethernet interface of the product is classified as "TNV-1" and offers protection against overvoltages of up to
1.5 kV.
Danger to life due to fire or explosion
In rare cases, an explosive gas mixture can be generated inside the product under fault conditions. In this state,
switching operations can cause a fire inside the product or explosion. Death or lethal injuries due to hot or flying
debris can result.
• In the event of a fault, do not perform any direct actions on the product.
• Ensure that unauthorized persons have no access to the product.
• Disconnect the battery from the product via an external disconnection device.
• Disconnect the AC circuit breaker, or keep it disconnected in case it has already tripped, and secure it against
reconnection.
• Only perform work on the product (e.g., troubleshooting, repair work) when wearing personal protective
equipment for handling of hazardous substances (e.g., safety gloves, eye and face protection, respiratory
protection).
