If you control the safety functions in the inverter using digital inputs, you must check whether
these digital inputs are connected to a "standard" function.
Proceed as follows to check as to whether the safety-related inputs are only used for the
safety functions:
1. In the project navigator, select the inputs/outputs.
2. Select the screen for the digital inputs.
3. Remove all digital input interconnections that you use as safety-related input F-DI:
Figure 8-52 Removing the DI 4 and DI 5 digital-input connections
4. You must delete the digital input connections for all CDS if you use the switchover of the
command data sets (CDS).
You can find a description of the CDS switchover in the operating instructions.
You have ensured that the safety-related inputs only control safety functions in the inverter.
