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 and deflagration
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 and, in very rare cases, a
deflagration inside the product. Death or lethal injuries due to the spread of a fire can result.
• In the event of a fault, do not perform any direct actions on the product.
• In the event of a fault, ensure that unauthorized persons have no access to the product.
• In the event of a fault, disconnect the PV module from the inverter via an external
disconnection device. If there is no disconnecting device present, wait until no more DC
power is applied to the inverter.
• In the event of a fault, disconnect the battery from the product via an external disconnection
service. Do not operate the DC load-break switch on the product.
• In the event of a fault, disconnect the AC circuit breaker, or keep it disconnected in case it
has already tripped, and secure it against reconnection.
Risk of injury due to toxic substances, gases and dusts.
In rare cases, damages to electronic components can result in the formation of toxic substances,
gases or dusts inside the product. Touching toxic substances and inhaling toxic gases and dusts
can cause skin irritation, burns or poisoning, trouble breathing and nausea.
• 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).
• Ensure that unauthorized persons have no access to the product.
