MENNEKES recommends using the data lines be-
low:
n With a line length of 40 m, a network cable
(CAT-6 / CAT-7) can be used. It can be useful to
use a network cable so that your installation is
ready to accommodate future developments.
Not all wires are required.
n PROFIBUS cable
n For installation in the ground: Siemens
PROFIBUS line, underground cable
6XV1830-3FH10 (manufacturer EAN
4019169400428)
n For installation without mechanical stress:
Siemens PROFIBUS line 6XV1830-0EH10
(manufacturer EAN 4019169400312)
Data lines must not exceed a length of 100 m.
Connection
A shield clamp and two cable ties are needed to
connect the data line. These are included in the de-
livery contents.
Fig. 10: Data line connection [mm]
Attach shield clamp:
u Strip the data line by 8 mm at a length of
115 mm.
u Attach the shield clamp at the stripped point.
u Use a cable tie to fix the shield clamp in place at
the jacket.
Connect the data line:
u Strip the data line.
u Strip the conductors 10 mm.
u Connect the protective shield to terminal 9
(XG2).
u Connect the twisted-pair cables to terminals 7
and 8 (XG2).

u Use a cable tie to fix all wire pairs in place.
u Insulate the used wire pairs (contact guard).
Attaching termination resistors at the ends of the
data line (optional)
If it is not possible to establish a stable connection
with the Modbus subscribers, we recommend ter-
minating both ends of the data line using 120 Ohm
resistors. Terminating the ends will reduce reflec-
tions and increase communication stability. The
need for terminating the ends of wires is dependent
on the installation environment (e. g. cable length,
number of Modbus subscribers). A general specific-
ation regarding the use of termination resistors can
therefore not be provided.
