Cabling Recommendations

Siemens recommends using SIMATIC NET industrial Ethernet shielded cables for all
Ethernet ports.
1.5.1

Protection On Twisted-Pair Data Ports

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 electri-
cal event, communications errors or interruptions may occur, but recovery is auto-
matic.
Siemens also does not recommend using copper Ethernet ports to interface with de-
vices 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.
