Magnetic capacitance with inductive loads
Note that an inductive load connected to the DO channels can induce voltages in the case of
electromagnetic interference of a strong magnetic field. This can cause a short-circuit error
• Spatially disconnect the inductive loads or shield against the magnetic field.
• Set the parameters for the readback time to 50 ms or higher.

The SF LED and the status displays of the inputs/outputs are not designed for safety-
related functions and may therefore not be evaluated for safety-related activities.
