Figure 4 - RS940G Power Supply Inputs
The RS940G AC power supply inputs should be connected as follows:
1. +/L should be connected to AC Line/Hot.
2. -/N should be connected to AC Neutral.
3. Surge Ground should be connected to the Chassis Ground via a braided cable or other
appropriate grounding wire. Surge Ground is used as the ground conductor for all surge
and transient suppression circuitry internal to the unit.
4. Chassis Ground must be connected to the AC ground terminal.
NOTES:
1. Equipment must be installed according to the applicable country wiring codes.
2. All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases
where users require the inputs to be isolated from ground, remove the ground braid
between Surge and Chassis Ground. Note that all line-to-ground transient protection
circuitry will be disabled.

2.2.2 DC Power Supply Wiring and Grounding
Figure 5 - DC Power supply wiring and grounding diagram
The RS940G low voltage DC power supply features reverse polarity protection and dual
independent inputs. The latter feature allows the connection of two DC sources with the same
nominal voltage to provide redundant power supply inputs.
The RS940G DC power supply inputs should be connected as follows:
1. Connect to the DC inputs according to the polarity markings on the unit.
2. Surge Ground should be connected to the Chassis Ground via a braided cable or other
appropriate grounding wire. Surge Ground is used as the ground conductor for all surge
and transient suppression circuitry internal to the unit.
3. Chassis Ground must be connected to the protective earth.
NOTES:
1. Equipment must be installed according to the applicable country wiring codes.
2. All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases
where users require the inputs to be isolated from ground, remove the ground braid
between Surge and Chassis Ground. Note that all line-to-ground transient protection
circuitry will be disabled.

2.2.3 Dielectric Strength Testing
Units which are to have dielectric strength testing (HIPOT testing) done in the field must have the
braided ground cable disconnected during the test. This is required in order to prevent the surge
suppression circuitry, which is connected to surge ground, from being activated.

2.3 Failsafe Output Wiring
The Failsafe output relay is provided to signal critical error conditions that may occur on the
RS940G. The contacts are energized upon power up of the unit and remain energized until an
alarm condition or power loss occurs. The behavior of the failsafe relay is configurable via the
RuggedSwitch Operating System. Consult the RuggedSwitch Users Guide for details.

2.4 RS232 Console Port Wiring
The RS232 port is used for configuring the RS940G. A straight-through serial cable with a DB-9
connector is required. There is no need to crossover the TxD and RxD signals from the PC side
since this has been done internally as is shown in the figure below.

2.5 Gigabit Ethernet
2.5.1 Copper 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 meters using 4 pairs of 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. To
ensure reliable, error-free data communications, new and pre-existing communication paths should
be verified for TIA/EIA-568-A compliance. Table 2 summarizes cabling standards available today
Cabling
Category 1000BaseTx Compliant Required action
< 5 No New wire infrastructure required
5 Yes Verify TIA/EIA-568-A compliance
5e Yes
No action required. New installations should be designed with
Category 5e components or higher
6 Yes No action required
> 6 Yes Connector and cabling standards to be determined.
Table 2: Cabling categories and 1000BaseTx compliance defined.
In general the following recommendations should be followed 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.
NOTE: 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
recommended to use 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.

Installation
2.5.2 Fiber Optical Transceiver
Depending on the order code of the product, the RS940G can be equipped with several different
types of fiber optic ports. The Transmit (TX) and Receive (RX) connections of each port must be
properly connected and matched for proper link and operation.
The drawings in the following figures show each fiber optical connector style with a side and top
view to allow the user to identify the proper cable connection orientation.

Installation
2.5.3 Pluggable optics – Installation, removal, and precautions
The RS940G can be ordered with pluggable optic form factors such as SFP (Small Form-factor
Pluggable). These 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 prevent the accumulation of
residue or particles that may inhibit proper operation.
Ensuring that the user has properly discharged any possible electrostatic build-up and
electrostatic discharges (ESD). This can be accomplished by properly user ‘grounding’ via an
ESD wrist strap, or by touching earth or chassis ground before performing installation or
removal of optics. ESD can damage or shorten the life of optical modules when not plugged
into a chassis.
SFP and GBIC optical modules should always be stored in an ESD safe bag or other suitable
ESD safe environment, free from moisture and stored at proper storage temperature (–40 to
+85C).
Disconnect all cables from SFP or GBIC module before insertion or removal of module.
Only RuggedCom Inc. certified optics should be used on RuggedCom products. Damage can
occur to optics and product if compatibility and reliability have not been properly assessed.
2.5.4 Module Insertion – SFPs
To insert SFPs, special attention should be taken into the proper module orientation. SFPs should
be inserted with dust cover in place, and the bail-latch in the locked position. Module should gently
slide into port and should lock in place when module is fully inserted. To protect optics, dust
covers should always be installed when cables are not connected.
2.5.5 SFP Module Removal
SFP Modules are removed using the metal bail latch located on the top of the module shown in
Figure 12. To remove the SFP module, disconnect any cable and replace with dust cover to
protect the optics. User should grasp bail latch and gently pull outwards to unlock and remove the
SFP module. Removal of the SFP module is shown further in Figure 13. The module should be
immediately stored in an ESD-safe environment.

and off for ports operating in 10/100BaseTX mode. The link/activity LED will be solid for ports with
link, and will blink for activity. The diagram in Figure 14 highlights the port and the associated
speed and link/activity LED.
