Cabling Recommendations
Siemens recommends using RUGGEDCOM industrial Ethernet shielded cables for all
Ethernet ports.
Siemens does not recommend the use of copper cabling of any length for critical,
real-time substation automation applications. 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
1 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.
