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 are integrated in the existing overvoltage
protection.
• When laying the network cable outdoors, ensure that there is suitable surge protection at
the network cable transition from the product outdoors to the network inside the 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 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.
• Do not operate the AC or DC load-break switch on the inverter in case of an error.
• Disconnect the PV array 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.
• Disconnect the AC circuit breaker, or keep it disconnected in case it has already tripped,
and secure it against reconnection. Do not operate the AC load-break switch on the
product.
• 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).
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.
