2.6.6 Serial Port Transient Protection
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.
