Terminal assignment
The following diagrams show wiring examples. Basically, these connection examples apply
to all channels (channel 0 to 7).
Note
When connecting voltage and current transducers, make sure the maximum permitted
common-mode voltage C
MV
of 2 V is not exceeded between the inputs. To prevent
measuring errors, interconnect the various M- terminals.
