Instrumentation and telecommunication cables may be routed on system 2 cable support
systems when the defined distance between the individual systems can be kept.
When separation of the cable systems specified above is not possible or practical, a metal
segregation barrier shall be installed to avoid induced disturbances on the
instrument/telecommunication cables.
However, crossing at right angles is acceptable without further segregation.
Non IS, IS instrument cables and Foundation Fieldbus shall be routed on the same cable
