Cabling Recommendations
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.

Tamper-Evident Security Seals
In compliance with the security requirements of the Federal Information Processing
Standards (FIPS140-2), FIPS-compliant tamper-evident security seals are applied
to potential access points on this device. Security seals provide evidence of
unauthorized tampering or removal of components.
Worn, damaged or missing seals must be replaced immediately.
Replacement seals are available for purchase from Siemens. For more information,
