RUGGEDCOM RX1501
Installation Manual, 05/2020, C79000-G8976-1054-17 3
Introduction
1.5.1Protection On Twisted-Pair Data Ports
1.5.1 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 electri-
cal event, communications errors or interruptions may occur, but recovery is auto-
matic.
Siemens also does not recommend using copper Ethernet ports to interface with de-
vices 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.
1.5.2 Gigabit Ethernet 1000Base-TX Cabling Recommendations
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbit/s Ethernet commu-
nications 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 de-
signers 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
1000Base-
TX Compliant Required Action
< 5 No New wiring infrastructure required.
5 Yes Verify TIA/EIA-568-A compliance.
5e Yes No action required. New installations should be designed with Cate-
gory 5e or higher.
6 Yes No action required.
> 6 Yes Connector and wiring standards to be determined.
Follow these recommendations for copper data cabling in high electrical noise envi-
ronments:
• 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 communica-
tions.
• 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.

fied herein may result in hazardous radiation exposure.
WARNING
Radiation hazard – risk of Radio Frequency (RF) exposure.
This device is compliant with the requirements set forth in FCC 47 CFR, section
1.1307, addressing Radio Frequency (RF) exposure from radio frequency base sta-
tions, as defined in FCC OET Bulletin 65 [http://transition.fcc.gov/Bureaus/Engi-
neering_Technology/Documents/bulletins/oet65/oet65.pdf]. The emitted radiation
should be as little as possible. To achieve minimum RF exposure, install the device
when it is configured not to transmit and set it to operational mode remotely, rather
than having a technician enable transmission on-site. For maintenance of the base
station, or other operations which require RF exposure, the exposure should be min-
imized in time and according to the regulations set forth by the country of installa-
tion or the Federal Communications Commission (FCC).
