2.1 DIN Rail Mounting
An optional IN rail mounting bracket is available for the RS900G. Figure 2.1.1 details mounting
instructions for the standard 1” IN Rail.

2.2 Power Supply Wiring and Grounding
2.2.1 HI Power Supply Wiring and Grounding
Figure 2.2.1 RS900G Family Power Supply Inputs
The RS900G family HI power supply inputs are identical and are connected as follows:
1. +/L should be connected to AC (Hot)
2. -/ should be connected to AC (Neutral)
3. Surge Ground is 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 RS900G unit.
4. Chassis Ground should be connected to the AC Ground terminal
otes:
1. Equipment must be installed according to the applicable country wiring codes.
2. Surge Ground MUST be disconnected from the Chassis Ground during HIPOT (dielectric
strength) testing.
3. 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 2.2.2.1 C Power supply wiring and grounding diagram
The RS900 low voltage C power supply features reverse polarity protection and dual independent
inputs. This feature allows the connection of two C sources with the same nominal voltage to
provide redundant power supply inputs. The C source must be connected to the C inputs
according to the polarity markings on the unit.
otes:
1. Equipment must be installed according to the applicable country wiring codes.
2. Surge Ground should be connected to Chassis Ground via a braided cable or other
appropriate ground wire.
3. Chassis Ground must be connected to the protective earth.
4. All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases
where users require the C 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.

2.3 HIPOT (Dielectric Strength) Testing
Units which are to be “HIPOT” tested in the field must have the braided ground cable disconnected
(see Figure 2.3.1) during the HIPOT test. This is required in order to prevent the transient/surge
suppression circuitry, which is connected to Surge Ground (see Figure 2.3.1), from being activated
during the HIPOT test.

2.4 Failsafe Output Wiring and Specifications
The “Failsafe” output relay is provided to signal critical error conditions that may occur on the
RS900G series switch. The contacts are energized upon power up of the unit and remain
energized until an alarm condition or power loss occurs.

2.5 RS232 Port Wiring
The RS232 port is used for configuring the unit. A straight-through serial cable with a B-9
connector is required. There is no need to crossover the Transmit and Receive signals from the PC
side since this has been done internally as shown in the figure below.

2.6 RJ45 Ports – Signal Description
The RS900G series switches have several 10/100BaseTX ports that allow connection to standard
CAT-5 UTP cable with RJ45 male connectors. The RJ45 receptacles are directly connected to the
chassis ground on the unit and can accept shielded CAT-5 cables. If shielded cables are used,
care must be taken to ensure the shielded cables do not form a ground loop via the shield wire and
the RJ45 receptacles at either end. Fig. 2.6.1 shows the RJ45 port pins configuration.

Case Shield (Chassis Ground)
Fig. 2.6.1 shows the RJ45 port pins configuration.
OTE: RuggedCom does not recommend the use of CAT-5 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.
