in the following picture. The polarity does not play any role here.
If a bus connection is not present, connect a separate power source with the following values
to terminals 6/7:
● With intrinsically-safe devices: intrinsically-safe isolating power supply with 24 V DC
● With non-intrinsically-safe devices: 15 to 30 V DC
Then match the positioner to the respective actuator by configuring and initializing it. Finally set
the bus address.
