2 Safety
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 battery from the product via an external disconnection
service.
• 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.
Danger to life due to fire when failing to observe torque specifications on live
bolted connections
Failure to follow the specified torques reduces the ampacity of live bolted connections and the
contact resistances increase. This can cause components to overheat and catch fire. Death or
lethal injuries can result.
• Ensure that live bolted connections are always tightened with the exact torque specified in
this document.
• Only use suitable tools when working on the device.
• Avoid repeated tightening of live bolted connections as this may result in inadmissibly high
torques.
