If the device represents the final station on the bus, then the looped‐through Profibus must be actively
terminated at both ends with a bus termination resistor between A and B.
At closed housings it is necessary to order with termination adjusted the right way, otherwise it is mandatory to
adapt an external resistor. For a good signal transmission it is necessary to terminate PROFIBUS segments by a
bus termination. For PROFIBUS RS 485 a bus termination consists of a combination of three resistors.
Connect the Termination resistors to lead 8 and 9 (BUS_A) and ( BUS_B) and for the active power lines to lead 6
and 7.
