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.
