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 1000 V or higher.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• Do not touch any parts other than the lower enclosure lid of the inverter during operation.
Damage to the enclosure seal in subfreezing conditions
If you open the inverter when temperatures are below freezing, the enclosure seals can be
damaged. This can lead to moisture entering the inverter.
• Only open the inverter if the ambient temperature is not below -5°C.
• If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the inverter (e.g. by melting the ice with warm air).
Damage to the inverter due to sand, dust and moisture
Sand, dust and moisture penetration can damage the inverter, thus impairing its functionality.
• Only open the inverter if the humidity is within the thresholds and the environment is free of
sand and dust.
• Do not open the inverter during a dust storm or precipitation.
• Close the inverter in case of interruption of work or after finishing work.
