2 Installation 2.1 Din Rail Mounting An optional DIN rail mounting bracket is available for the RS910W. The figure below details mounting instructions for the standard 1” DIN Rail. Figure 3 - RS910W DIN Rail Mounting 8 2007 RuggedCom Inc.
2.2 Power Supply Wiring and Grounding 2.2.1 AC Power Supply Wiring and Grounding Figure 4 - RS910W Power Supply Inputs The RS910W 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.
2.2.2 DC Power Supply Wiring and Grounding Figure 5 - DC Power supply wiring and grounding diagram The RS910W 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 RS910W DC power supply inputs should be connected as follows: 1. Connect to the DC inputs according to the polarity markings on the unit. 2.
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. Figure 6 - Dielectric Strength Testing 11 2007 RuggedCom Inc.
2.3 Failsafe Output Wiring The Failsafe output relay is provided to signal critical error conditions that may occur on the RS910W. 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. Figure 7 - RS910W Failsafe Output Relay 12 2007 RuggedCom Inc.
2.4 RS232 Console Port Wiring The RS232 port is used for configuring the RS910W. 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.
3 Serial Ports The RS910W can be equipped with a Fiber Serial Interface, RS232/RS485/RS422 DB9 serial ports or RS232/RS485/RS422 RJ45 serial ports. 3.1.1 Fiber Serial Interface The RS910W can be equipped with a Fiber Serial Interface (ST connector only) which allows RS485, RS422, or RS232 devices to communicate over secure, noise immune, optically isolated, fiber optic cabling at extended distances as well as protocol independent conversion to multimode fiber optics.

Figure 12: Conceptual recommended RS485 wiring diagram 3.1.5 Serial Port Transient Protection 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.
4 Ethernet Ports 4.1 RJ45 Ethernet Ports The RS910W has several 10/100Base-TX ports that allow connection to standard category 5 (CAT-5) unshielded twisted-pair (UTP) cable with RJ45 male connectors. The RJ45 receptacles are directly connected to the chassis ground on the unit and can accept CAT-5 shielded twistedpair (STP) 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.
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. 4.2 Fiber Optic Ethernet Ports Depending on the order code of the product, the RS910W can be equipped with several different fiber optic ports. The Transmit (Tx) and Receive (Rx) connections of each port must be properly connected and matched for proper link and operation.

8 Appendix A - RuggedWireless ™ Frequently Asked Questions (FAQ) What factors can affect wireless coverage/range? Range estimates are typical and require line of sight. Basically that means you will need a clear unobstructed view of the antenna from the remote point in the link. Keep in mind that walls and obstacles will limit your operating range and could even prevent you from establishing a link. Signals in the 2.4 Ghz generally will not penetrate metal or concrete walls.
