Terminal assignment
The diagrams below show various wiring options. These examples apply to all channels
(channel 0 to 7).
Note
When connecting voltage and current transducers, make sure that the m
aximum permitted
-mode voltage C
MV
of 2 V is not exceeded between the inputs. Prevent measuring
errors by interconnecting the corresponding M
- terminals.
