• Optionally, shielded/screened cabling can be used. The cable shield should be grounded at one

single point to avoid the generation of ground loops.

3.5.3. Transient Suppression

All copper Ethernet ports on RuggedCom products include transient suppression circuitry to protect

against damage from electrical transients and to ensure conformance to IEC 61850-3 and IEEE 1613

Class 1. This means that during a transient electrical event, it is possible for communications errors

or interruptions to occur, but recovery is automatic.

RuggedCom does not recommend the use of copper cabling of any length for critical, real-

time, substation automation applications.

RuggedCom also recommends against the use of copper Ethernet connections to interface to devices

in the field across distances which could produce high levels of ground potential rise (that is, greater

than 2500V) during line-to-ground fault conditions.

Depending on the product order code, the RuggedBackbone™ RX5000 can be equipped with LMs and

SMs with several different types of fiber optic ports. The Transmit (TX) and Receive (RX) connections

of each port must be properly connected and matched for proper link establishment and operation.

The following figures show the front and top views of each supported fiber optic connector type to

assist in identifying the proper cable connection orientation.
