In general the following recommendations should be followed for copper data cabling in high

electrical noise environments:

 Data cable lengths should be as short as possible, ideally limited to 3m (10ft) in length.

Copper data cables should not be used for inter-building communications.

 Power and data cables should not be run in parallel for long distances, and ideally should be

installed in separate conduits. Power and data cables should intersect at 90 angles when

necessary to reduce inductive coupling.

 Shielded/screened cabling can optionally be used. The cable shield should be grounded at

one single point to avoid the generation of ground loops.

NOTE: RuggedCom does not recommend the use of copper cabling of any length for critical real-

time substation automation applications. However, transient suppression circuitry is present on all

copper ports to protect against damage from electrical transients and to ensure IEC 61850-3 and

IEEE 1613 Class 1 conformance. This means that during the transient event communications

errors or interruptions may occur but recovery is automatic. RuggedCom also does not

recommended to use these ports to interface to field devices across distances which could produce

high levels of ground potential rise, (i.e. greater than 2500V) during line to ground fault conditions.
