Cabling Recommendations

Siemens recommends using SIMATIC NET industrial Ethernet shielded cables for all Ethernet ports.
Refer to the following sections for further recommendations and considerations:
• Section 2.6.1, "Protection On Twisted-Pair Data Ports"
• Section 2.6.2, "Gigabit Ethernet 1000Base-TX Cabling Recommendations"
Section 2.6.1

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 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.
