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.
WARNING
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.
WARNING
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 measurement ranges designed for the maximum AC and
DC voltage of the inverter.
CAUTION
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.
• Wait until the inverter has cooled down before touching the enclosure.
