Faulty wiring can lead to malfunctions as well as damage to
the bus system.
O
Unless otherwise stipulated, comply with the
construction and design directives for the PROFIBUS DP/
FMS (PROFIBUS directive, PNO order no. 2.111).
O
Only a cable that meets the fieldbus specifications as
well as the connection speed and length requirements
should be used.
O
In order to assure both the protection class and the
required strain relief, the cable and plug assembly
should be done professionally.
Current flow in shield due to differences in potential
Compensating currents caused by differences in potential
must not flow over the shield of the bus cable, as this will
remove the shielding, which could damage the line and
connected bus coupler.
O
If necessary, connect the grounding points for the system
using a separate line.
