Basic circuit diagram: Transmission over copper cable
Key:
When a field multiplexer system is being installed for the first time, Phoenix Contact
recommends a 3-wire shielded cable. In this case, connector1 of both stations should be
connected to the DATA, DATA, and GND
DATA
signals and the shield (see also Section
“Terminal point assignment” on page 18). DATA and DATA should additionally be a twisted
pair.
Laying the remote bus cable
When laying the remote bus cable, note the following:
–
Do not lay signal and bus cables in parallel to power cables
–
If possible, lay remote bus cables and cables with voltages of 230 V and above in
separate cable ducts
–
Always lay signal leads and equipotential bonding together in one cable following the
shortest route
–
Avoid extending the remote bus cables with connecting plugs

Phoenix Contact recommends the remote bus cable IBS RBC METER-T
(Order No. 2806286, see also Section “Ordering data” on page 65 or the AUTOMATION
catalog).
