Laying Field Cables
There are no special requirements for laying field and communication cables
connected to AC 800M. However:
• Cables for short-distance communication without modems should always be
routed at a distance of 10 cm (4 in) from other cables.
• All cables connected to AC 800M should be routed at a distance of 30cm
(12 in) from all power cables and 10 cm (4 in) from cables belonging to the
relevant international immunity standard, class 4.
Type of Field Cable
Always use shielded cables for the following applications:
• Communications
• High-frequency pulse transmission
• Low level analog signals, for example Pt100 and thermocouples
Unshielded cables may be used for other applications. The signal and return
conductor should be located in the same cable.
Industrial installations and power plants are normally provided with well-integrated
grounding networks, installed as part of the power distribution system. Such
installations do not require additional lightning protection unless using overhead
wiring or suspended cables in an outdoor environment.
However, large dispersed plants such as water supply installations and oil refineries
will have an inadequate grounding system where signal cables may be routed above
ground. In such cases lightning protection equipment must be installed.
Should cables be discovered outside the grounding system (even at a short distance
such as 10 m [9.1 yds]) lightning protection equipment must be installed
