Installation instructions
The bus cables are supplied by the meter. If a bus segment must
be assembled using two sections (e.g. > 1 000 m segment
length), bushings can be used for this purpose (low-impedance
connection between cores with clamps, connect shields over a
wide area).
FastConnect
The FastConnect stripping tool can be used to strip the outer
sheath and shield of the new FastConnect bus cables to the right
length in one step.
In this way, the bus connectors (except 6ES7972-0BA30-0XA0)
can be connected easily and quickly to the bus cable.
Migration in discrete automation
For many years, PROFIBUS has been the established fieldbus
for machines and plants and with the wider use of Ethernet in IT
and PROFINET in industry, production systems today would be
unimaginable without either of these systems.
For migration from PROFIBUS to PROFINET or Industrial
Ethernet in discrete automation, Siemens offers a solution in
which the existing two-wire cabling for Ethernet communication
can be used.

Cable routing:
During storage, transport and cable laying, keep both ends
sealed with a shrink-on cap.
Comply with the permissible bending radii and tensile load!
An underground cable must be used if cables are laid outside
buildings e.g. directly in the ground, in sand or in concrete build-
ing blocks or when routed through protective pipes made of
steel or plastic above or below ground.
Comply with overvoltage protection guidelines for underground
laying.
Note:
You can order components supplementary to the SIMATIC NET
cabling range from your local contact.
