Wiring the multiNet plus

Leuze multiNet plus connection hints
Shielded, twisted pair conductors should be used for the Leuze multiNet plus. This allows a
total network length of up to 1200m.
Recommended network cable (e.g. LiYCY 2x0.2mm²):
- Twisted pairs, shielded
- Cross section: min. 0.2mm²
- Copper resistance <100Ω/km
When wiring the network, note the following points:
• The RS 485A, RS 485B and GND lines are wired through in the network and must not
in any case be misconnected; the Leuze multiNet plus network is otherwise not func-
tional. It is recommended that the GND of the RS 485 interface of the participants be
wired through with the other wires.
• Connect the shielding to the slaves with FE.
• The maximum line length in the network is 1200m.
• The (physically) last slave in the network should be fitted with a terminating resistor of
220Ω between RS 485A and RS 485B. This prevents reflections on the multiNet plus
and improves the interference immunity.
Notice!
Use the recommended connectors / sockets or the ready-made lines and terminating resis-
tors (see chapter 13 "Type overview and accessories").
