Danger to life due to fire and deflagration
In rare cases, an explosive gas mixture can be generated inside the inverter under fault
conditions. In this state, switching operations can cause a fire and, in very rare cases, a
deflagration inside the inverter. Death or lethal injuries due to the spread of a fire can result.
• In case of failure, do not perform any direct actions on the inverter.
• In case of failure, ensure that unauthorized persons have no access to the product.
• In case of failure, 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 case of failure, disconnect the battery from the inverter via an external disconnection
device. Do not operate the DC load-break switch on the inverter.
• 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 inverter. 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 inverter (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 inverter.
Danger to life due to fire or explosion when batteries are fully discharged
A fire may occur due to incorrect charging of fully discharged batteries. This can result in death
or serious injury.
• Before commissioning the system, verify that the battery is not fully discharged.
• Do not commission the system if the battery is fully discharged.
• If the battery is fully discharged, contact the battery manufacturer for further proceedings.
• Only charge fully discharged batteries as instructed by the battery manufacturer.
