The following cable types are suitable for non-hazardous areas, for example:
• Siemens 6XV1 830-5BH10
• Belden 3076F
• Kerpen CEL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL
Maximum overall cable length
The maximum network expansion depends on the type of protection and the cable
specifications. The overall cable length comprises the length of the main cable and the length
of all spurs >1 m (3.28 ft).
The maximum overall cable length for cable type A: 1 900 m (6 200 ft)
If repeaters are used, the maximum permitted overall cable length is doubled. A maximum of
three repeaters are permitted between the user and master.
Maximum spur length
The line between the distribution box and field device is described as a spur. In the case of
applications in non-hazardous areas, the max. length of a spur depends on the number of
spurs >1 m (3.28 ft):

Number of field devices
For systems designed in accordance with the Fieldbus Intrinsically Safe Concept (FISCO) with
EEx ia types of protection, the cable length is limited to a maximum of 1 000 m (3 300 ft). A
maximum of 32 users per segment in non-hazardous areas or a maximum of 10 users in
