Grounding the Device
The RX1100 chassis ground terminal uses a #6-32 screw. It is recommended to terminate the ground connection
with a #6 ring lug and torque it to 1.7 N·m (15 lbf·in).

Cabling Recommendations
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.
