3.7 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 recommend using 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.
