Assembly
Faulty wiring
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 use cables that meet the field bus specifications as
well as the connection speed and length requirements.
O
In order to assure the protection class, the shielding, and
the required strain relief, the cable and plug assembly
should be done professionally.
Current conduction via differences in potential on the shield
Compensating currents caused by differences in potential
must not flow through the shield of the PROFIBUS cable, as
this will cancel 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.
