PROFIBUS PA cable specifications
Twisted, shielded pairs must be used. The following specification must be met for explosion
hazardous application (EN 50 020, FISCO model):
• Loop-resistance (DC): 15 to 150
/km
• Specific inductance: 0.4 to 1 mH/km
• Specific capacitance: 80 to 200 nF/km
The following cable types can be used, for example:
Non-Ex-area:
• Siemens 6XV1 830-5BH10 (black)
• Kerpen CEL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL (gray)
• Belden 3076F (orange)
Ex-area:
• Siemens 6XV1 830-5AH10 (blue)
• Belden 3076F
• Kerpen CEL-PE/OSCR/PVC/FRLA FB-02YS(ST+C)YFL (blue)

Supply voltage
The following values are the voltages across the terminals directly at the device:
Approx. 11 mA for the range of voltages given above.

Potential equalization
CAUTION
!
Applications, which are subject to the explosion prevention, permit only under special
conditions the repeated grounding of the protective screen , see to EN 60079-14.

For maximum EMC protection please observe the
following points:
• The external ground terminal on the
transmitter must be connected to ground.
The cable should be kept as short as possible for
optimum electromagnetic compatibility. The
use of a grounding strip is ideal.
• The continuity of the cable shielding between
tapping points must be ensured.
• If potential equalization is present between the
individual grounding points, ground the
shielding at each cable end or connect it to the
device housing (as short as possible).
• If there are large differences in potential
between grounding points, the grounding
should run via a capacitor that is suitable for
high frequency use
(e.g. ceramic 10 nF/250 V&).
