Introduction 1
The RUGGEDCOM RS920L is a utility-grade serial device server and managed Ether-
net switch supporting Ethernet over VDSL (EoVDSL). The RUGGEDCOM RS920L can
be configured with two serial ports (RS485/RS422/RS232) and up to EoVDSL ports.
EoVDSL supports LAN segments of up to 5 km (3.1 mi) over telephone grade cable
(or other legacy serial cabling) at up to 35 Mbps (upstream and downstream). It al-
lows an Ethernet-enabled device to communicate with a central control room using
existing cabling. It is the perfect solution for bringing Ethernet networking to serial
devices in remote locations and applications where existing wiring is already present,
thus saving the considerable cost of upgrading existing legacy devices or installing
new network cabling.
The RUGGEDCOM RS920L provides a high level of immunity to electromagnetic in-
terference and heavy electrical surges typical of environments found on plant floors
and curb-side traffic control cabinets. An operating temperature range of -40 to 85 °C
(-40 to 185 °F) coupled with hazardous location certification (Class I Division 2), op-
tional conformal coating and a galvanized steel enclosure allows the RUGGEDCOM
RS920L to be placed in almost any location.
The RUGGEDCOM RS920L can be mounted on a DIN rail or panel for efficient use of
cabinet space.
The integrated power supply supports a wide range of voltages (88-300 VDC or
85-264 VAC) for worldwide operability, as well as dual-redundant, reversible polari-
ty, 24 VDC and 48 VDC power supply inputs for high availability applications requir-
ing dual or backup power inputs.
The RUGGEDCOM RS920L 's superior ruggedized design and embedded RUGGEDCOM
Rugged Operating System (ROS) provides superior system reliability and advanced
networking features making it ideally suited for creating Ethernet networks for mis-
sion-critical, real-time, control applications.

Introduction
1.3Required Tools and Materials
1.3 Required Tools and Materials
The following tools and materials are required to install the RUGGEDCOM RS920L:
Tools/Materials Purpose
AC power cord (16 AWG) For connecting power to the device.
CAT-5 Ethernet cables For connecting the device to a LAN.
Flathead screwdriver For mounting the device to a DIN rail.
Phillips screwdriver For mounting the device to a panel.
4 x #6-32 screws For mounting the device to a panel.
1.4 Decommissioning and Disposal
Proper decommissioning and disposal of this device is important to prevent malicious
users from obtaining proprietary information and to protect the environment.
Decommissioning
This device may include sensitive, proprietary data. Before taking the device out of
service, either permanently or for maintenance by a third-party, make sure it has
been fully decommissioned.
For more information, refer to the associated Configuration Manual.
Recycling and Disposal
For environmentally friendly recycling and disposal of this device and related acces-
sories, contact a facility certified to dispose of waste electrical and electronic equip-
ment. Recycling and disposal must be done in accordance with local regulations.
1.5 Cabling Recommendations
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 I 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.

3. Verify all items are included.
NOTICE
If any item is missing or damaged, contact Siemens for assistance.
2.2 Installing the Device in Hazardous Locations
The RUGGEDCOM RS920L is designed to comply with the safety standards for Class I,
Division 2 hazardous locations where concentrations of flammable gases, vapors or
liquids may be present, as opposed to normal operating environments.
IMPORTANT
The device is certified for installation in hazardous environments as a component
only. It is required to be installed in a suitable enclosure where the final combination
is subject to acceptance by an authorized local inspection authority.
Installation and use of the device in a hazardous location should meet the following
special conditions for safe use:
• The equipment should be installed in an enclosure that is considered to be not
accessible in normal operation without the use of a tool providing a degree of
protection of not less than IP54. The enclosure should have a minimum service
temperature range of -40 to 100 °C (-40 to 212 °F).
• The equipment should be used in an area of not more than pollution degree 2.
• The console port should only be used in the safe area.
• The equipment should be appropriately connected to safety Earth upon installa-
tion.
Note
For further details of the device's compliance with Class I, Division 2 standards, refer
to "Approvals (Page 33)".
IMPORTANT
Do not disconnect or open equipment unless power has been switched off or the
area is known to be non-hazardous.
IMPORTANT
Débrancher ou ouvrir l'équipment seulement si l'alimnetation a été coupée ou si l'on
sait que la zone ne pose aucun danger.
IMPORTANT
Substitution of the components may impair suitability for Class I, Division 2.
IMPORTANT
Le remplacement de composants pourrait compromettre l'admissibilité à la Classe I,
Division 2.

Installing the Device
2.3Mounting the Device
2.3 Mounting the Device
The RUGGEDCOM RS920L is designed for maximum mounting and display flexibility.
It can be equipped with adapters that allow it to be attached to a DIN rail or panel.
IMPORTANT
Heat generated by the device is channeled outwards from the enclosure. As such, it
is recommended that 2.5 cm (1 in) of space be maintained on all open sides of the
device to allow for some convectional airflow.
Forced airflow is not required. However, any increase in airflow will result in a reduc-
tion of ambient temperature and improve the long-term reliability of all equipment
mounted in the rack space.
Note
For detailed dimensions of the device with either DIN rail or panel hardware installed,
refer to "Dimension Drawings (Page 30)".
2.3.1 Mounting the Device on a DIN Rail
The RUGGEDCOM RS920L can be ordered with a DIN rail adapter preinstalled on the
back of the chassis. Use the adapter to mount the device to a standard 35 mm (1.4
in) IEC/EN 60715 or TS35 DIN rail.

2.3.2 Mounting the Device to a Panel
For panel installations, the RUGGEDCOM RS920L can be equipped with panel
adapters on the top and bottom of the chassis. The adapters allow the device to be
attached to a panel using screws.
To mount the device to a panel, do the following:
1. Prepare mounting holes in the panel where the device is to be installed.

3. Secure the adapters to the panel with #6-32 screws.
2.4 Connecting the Failsafe Alarm Relay
The failsafe relay can be configured to latch based on alarm conditions. The NO
(Normally Open) contact is closed when the unit is powered and there are no ac-
tive alarms. If the device is not powered or if an active alarm is configured, the relay
opens the NO contact and closes the NC (Normally Closed) contact.
Note
Control of the failsafe relay output is configurable through RUGGEDCOM RS920L .
One common application for this relay is to signal an alarm if a power failure occurs.
For more information, refer to the RUGGEDCOM RS920L User Guide for the RUGGED-
COM RS920L.
To connect the failsafe alarm relay, do the following:
1. Insert the failsafe alarm relay terminal block into the device and tighten the
screws.

2.5 Connecting Power
The RUGGEDCOM RS920L supports power input from a single high AC/DC or low DC
power supply.
IMPORTANT
• For 110/230 VAC rated equipment, an appropriately rated AC circuit breaker
must be installed.
• For 125/250 VDC rated equipment, an appropriately rated DC circuit breaker
must be installed.
• Use minimum #16 gage copper wiring when connecting terminal blocks.
• Equipment must be installed according to applicable local wiring codes and
standards.
• 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.
