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.
