For the measuring ranges that can be configured, plese refer to the sections Measuring Ranges
Ä Chapter 1.7.2.2.10 "Measuring ranges" on page 650 and Parameterization Ä Chapter
1.7.2.2.7 "Parameterization" on page 640.
To avoid error messages, configure unused analog input channels as "unused".
Connection of passive-type analog sensors (Current) to the analog inputs
The following figure shows the connection of passive-type analog sensors (current) to the
analog input AI0. Proceed with the analog inputs AI1 to AI3 in the same way.

NOTICE!
Risk of faulty measurements!
The negative pole/ground potential at the sensors must not have too large a
potential difference with respect to ZP (max. ± 1 V within the full signal range).
Make sure that the potential difference never exceeds ± 1 V.
