Endress+Hauser Prosonic M FMU40 - Fieldbus Plug Connectors; Supply Voltage

Prosonic M
12 Endress+Hauser
The digital communication signal is transmitted to the bus via a 2-wire connection. The bus also provides the
auxiliary energy. Use 2-wire twisted pair cable with screen.
Refer to the following operating manuals for information on cable types, and how to set up and ground the
network:
• BA00034S "PROFIBUS DP/PA: "Guidelines for planning and commissioning PROFIBUS DP/PA", PNO
Guideline 2.092 "PROFIBUS PA User and Installation Guideline" and IEC61158-2 (MBP).
• BA00013S "FOUNDATION Fieldbus Overview", FONDATION Fieldbus Guideline and IEC61158-2 (MBP).
Fieldbus plug connectors For the versions with fieldbus plug connector (M12 or 7/8"), the signal line can be connected without opening
the housing.
