3.5.2.3 Feedback Insulation Monitoring Device
The feedback contact of the insulation monitoring device can be queried via terminals
(-X2.9-11). The connection is provided as potential-free feedback contact.
Mode of operation of the insulation monitoring device:
If the measured value of the insulation resistance drops below the set threshold value,
the output relays switch into the fault state. If the measured value exceeds the
threshold value plus hysteresis, the output relays switch back into their original state.
