DANGER
Danger to life due to electric shock when touching live system components in
case of a ground fault
If a ground fault occurs, parts of the system may still be live. Touching live parts and cables
results in death or lethal injuries due to electric shock.
• Disconnect the product from voltage sources and ensure it cannot be reconnected before
working on the device.
• Only touch the cables of the PV modules on their insulation.
• Do not touch any parts of the substructure or frame of the PV array.
• Do not connect PV strings with ground faults to the inverter.
• Ensure that no voltage is present and wait 5 minutes before touching any parts of the PV
system or the product.
DANGER
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 1.5kV.
WARNING
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.
