Follow these recommendations for copper data cabling in high electrical noise
environments:
Data cable lengths should be as short as possible - ideally limited to 3m (10ft)
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
ideally 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 optionally be used. The cable shield should
be grounded at one single point to avoid the generation of ground loops.
2.7.3 Transient Suppression
RuggedCom does not recommend the use of copper cabling of any length for
critical, real-time, substation automation applications. However, transient
suppression circuitry is present on all copper ports to protect against damage
from electrical transients and to ensure IEC 61850-3 and IEEE 1613 Class 1
conformance. This means that during the transient event, communications errors
or interruptions may occur but recovery is automatic. RuggedCom also does not
recommend using these ports to interface to field devices across distances which
could produce high levels of ground potential rise, (i.e. greater than 2500V)
during line-to-ground fault conditions.
2.8 Pluggable optics – Installation, removal, and
precautions
The RSG2200 series of products can be ordered with pluggable optic form
factors: SFP (Small Form-factor Pluggable) or GBIC (Gigabit Interface
Converter). SFP and GBIC modules can be safely inserted and removed while
the chassis is powered and operating – this feature is also known as “hot-
swappable”. When inserting or removing optics, there are several precautions
that should be taken. They include:
Ensuring that dust caps are mounted on SFP cages at all times unless a user
is in the process of inserting or removing an SFP module. The dust caps will
