Wiring
NRG 16-41, NRG 17-41, NRG 19-41
Note that screened multi-core twisted-pair control cable is required for the BUS line, e. g. UNITRONIC ®
BUS CAN x x ... mm or RE-YCYV-fl x x ... mm .
Prefabricated control cables (with connector and coupler) of various lengths for connecting the
equipment are available as accessories.
The baud rate (data transfer rate) dictates the cable length between the bus nodes and the total power
consumption of the sensor dictates the conductor size.
The baud rate is set via a code switch. Reduce baud if cable is longer than specified in the table. Make
sure that all bus nodes have the same settings.
To protect the switching contacts fuse circuit with .5 A (anti-surge fuse) or according to TRD
regulations (.0 A for 7 hrs operation).
If a max. cable length of more than 125 m (up to 1000 m) is desired, make sure to modify the
baud rate settings accordingly. Please refer to pages 21 and 22.
