Fundamental safety instructions
1.1
General safety instructions
WARNING
Risk of death if the safety instructions and remaining risks are not carefully observed
WARNING
Danger to life or malfunctions of the machine as a result of incorrect or changed
parameterization
If the safety instructions and residual risks are not observed in the associated hardware
documentation, accidents involving severe injuries or death can occur.
• Observe the safety instructions given in the hardware documentation.
• Consider the residual risks for the risk evaluation.
As a result of incorrect or changed parameterization, machines can malfunction, which in
turn can lead to injuries or death.
• Protect the parameterization (parameter assignments) against unauthorized access.
• Respond to possible malfunctions by applying suitable measures (e.g. EMERGENCY
STOP or EMERGENCY OFF).

● Compact Operating Instructions in German and English
● The inverter contains open-source software (OSS). The OSS license terms are saved in
the inverter.
To transfer the OSS license terms from the inverter to a PC, proceed as follows:
1. Switch off the inverter power supply.
2. Insert an empty memory card into the card slot of the inverter. Also see Section:Overview
of the interfaces (Page 8)
3. Switch on the inverter power supply.
4. When you have switched on the power supply, wait 30 seconds.
During this time, the inverter writes the "Read_OSS.ZIP" file onto the memory card.
5. Switch off the inverter power supply.
6. Remove the card from the inverter.
7. Use a card reader and load the file to a PC.
