1.3 Notes on equipment configuration and installation
Always observe the current safety and accident prevention regulations when
commissioning the equipment.
Install the power, signal and sensor cables so as to prevent electromagnetic
interference from impairing operation of the equipment.
Install automation engineering equipment and installations with sufficient
protection against accidental actuation.
Take suitable precautions in both the hardware and software to prevent any
undefined states of the automation installation in the event of an open circuit.
In installations where major damage to property or even personal injury may
be caused by a malfunction, take suitable precautions to establish a safe
operating state in the event of a fault. This may be achieved using limit
switches, mechanical interlocks etc. for example.

3.1.1 Installation of fieldbus lines
For the PROFIBUS employing RS 485 transmission technology, all devices
are connected in a line structure. The bus line is a shielded twisted pair cable.
The fieldbus line is specified in EN 50 170 as cable type A and must comply
with specific cable parameters. Cable type B also specified in EN 50 170 is
obsolete and should no longer be used.
Parameter value
Characteristic impedance in Ω135 to 165 for 3 to 30 Mhz
Effective capacitance < 30 pF/m
Loop impedance (Ω/km) < 110
Wire diameter (mm) *) >0.64
Wire cross-section (mm2) *) >0.34
*) the wire cross-sections used must be suitable for the connection options on
the bus connector.
For cable type A, the maximum cable lengths for a bus segment depend on
the transfer rate.
Transfer rate Max. bus segment length
9.6 ... 93.75 kbaud 1200 m
187.5 kbaud 1000 m
500 kbaud 400 m
1500 kbaud 200 m
3000 / 6000 / 12000 kbaud 100 m

Installation
PROFIBUS manual Version FELD-V2002.02 Page 9
Commercially available connectors allow the incoming data cable to be
connected directly to the outgoing data cable in the connector. This avoids
stubs, and the bus connector can be connected to the bus or disconnected
from the bus at any time without interrupting data traffic. These connectors
include a bus termination that can be switched in or out. To avoid line
reflections, connectors containing integral series inductors should be used to
compensate for the capacitive load of the station. This is essential for transfer
rates > 1.5 Mbaud.

Wiring of bus lines with bus termination
Note
Take care not to swap over the data lines when connecting the stations.
Always install the bus termination at the start and end of the bus line. The
bus termination uses the supply voltage VP from the device, so ensure that
the voltage supply to the slave device on which the bus termination is
installed is always on.
Since the connectors contain built-in series inductors, avoid fitting connectors
that are not connected to field devices, because the non-existent device
capacitance may cause transmission errors.
It is essential to use a shielded PROFIBUS cable in order to achieve high
system immunity to radiated electromagnetic interference. As far as possible,
the shield should be connected at both ends to the protective ground via large-
area shielding clamps providing good conducting contact. In addition, ensure
that the cable is positioned as far as possible from all power cables. At data
rates >1.5 Mbit/s, stubs must be avoided at all costs.
An equipotential bonding conductor must be installed to reduce potential
differences introduced by different network input points from different parts
of the system.
