Danger to life due to fire or explosion
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 inside the inverter or explosion.
Death or lethal injuries due to hot or flying debris can result.
• Ensure that unauthorized persons have no access to the inverter.
• Do not remove the Electronic Solar Switch (ESS) from the inverter.
• 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.
• 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).
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 electric shock from destruction of the measuring device
due to overvoltage
Overvoltage can damage a measuring device and result in voltage being present in the
enclosure of the measuring device. Touching the live enclosure of the measuring device results in
death or lethal injuries due to electric shock.
• Only use measuring devices with a DC input voltage range of 800 V or higher.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation. Touching hot enclosure parts can
result in burn injuries.
• During operation, do not touch any parts other than the enclosure lid of the inverter.
