Cabling Recommendations

All copper Ethernet ports on RUGGEDCOM products include transient suppression

circuitry to protect against damage from electrical transients and conform with

IEC 61850-3 and IEEE 1613 Class I standards. This means that during a transient

electrical event, communications errors or interruptions may occur, but recovery is

automatic.

Siemens also does not recommend using copper Ethernet ports to interface with

devices in the field across distances that could produce high levels of ground

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