In order to prevent the safety-related inputs of the safety functions unintentionally controlling
"standard" functions in the inverter, proceed as follows:
1. Select the inputs/outputs in STARTER in the project navigator.
2. Select the screen for the digital inputs.
3. Remove all digital input interconnections that you use as safety-related input F-DI:
4. If you use the CDS dataset switchover, you must delete the digital input connections for
all CDS.
