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.
Section 2.3.2
Gigabit Ethernet 1000Base-TX Cabling Recommendations
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbit/s Ethernet communications over distances of up
to 100 m (328 ft) using all 4 pairs in category 5 (or higher) balanced, unshielded twisted-pair cabling. For wiring
guidelines, system designers and integrators should refer to the Telecommunications Industry Association (TIA)
TIA/EIA-568-A wiring standard that characterizes minimum cabling performance specifications required for proper
Gigabit Ethernet operation. For reliable, error-free data communication, new and pre-existing communication
paths should be verified for TIA/EIA-568-A compliance.
The following table summarizes the relevant cabling standards:
Cabling Category
< 5

5e

> 6
Follow these recommendations for copper data cabling in high electrical noise environments:
• Data cable lengths should be as short as possible, preferably 3 m (10 ft) in length. Copper data cables should
not be used for inter-building communications.
• Power and data cables should not be run in parallel for long distances, and should be installed in separate
conduits. Power and data cables should intersect at 90° angles when necessary to reduce inductive coupling.
• Shielded/screened cabling can be used when required. Care should be taken to avoid the creation of ground
loops with shielded cabling.
Section 2.4
Mounting the Device
The RUGGEDCOM RSG2300P is designed for maximum mounting and display flexibility. It can be equipped with
connectors that allow it to be installed in a 48 cm (19 in) rack, 35 mm (1.4 in) DIN rail, or directly on a panel.
IMPORTANT!
Heat generated by the device is channeled outwards from the enclosure. As such, it is recommended
that 2.5 cm (1 in) of space be maintained on all open sides of the device to allow for some
convectional airflow.
