13.4.3 PROFIBUS wiring
Requirements:
Do avoid tight bends in the PROFIBUS signal cable.
All devices in bus system must be connected in a line.
IP66 rated T adaptor must be used to connect pump to PROFIBUS line Maximum 32 stations (including master,
slaves and repeaters) are possible.
Both cable ends must be fitted with terminating resistor.
M12 socket provided for PROFIBUS installation are IP66 rated.
To maintain IP66 rated system—All PROFIBUS cables, T adaptors and terminating resistors used must be fitted
with IP66 rated M12 industrial connectors.
NOTE34
Only use certified PROFIBUS cables and connectors. Follow PROFIBUS guidelines for correct
installation.
NOTE35
If pump is last bus device connected to PROFIBUS cable; cable must be terminated using
terminating resistor (PROFIBUS standard EN 50170). Resistor must be IP66 rated.
