Cybersecurity information
Siemens provides products and solutions with industrial cybersecurity functions that
support the secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats,
it is necessary to implement – and continuously maintain – a holistic, state-of-the-
art industrial cybersecurity concept. Siemens' products and solutions constitute one
element of such a concept.
Customers are responsible for preventing unauthorized access to their plants,
systems, machines and networks. Such systems, machines and components should
only be connected to an enterprise network or the internet if and to the extent
such a connection is necessary and only when appropriate security measures (e.g.
firewalls and/or network segmentation) are in place.
For additional information on industrial cybersecurity measures that may be
implemented, please visit https://www.siemens.com/cybersecurity-industry.
Siemens' products and solutions undergo continuous development to make them
more secure. Siemens strongly recommends that product updates are applied as
soon as they are available and that the latest product versions are used. Use of
product versions that are no longer supported, and failure to apply the latest updates
may increase customer's exposure to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial
Cybersecurity RSS Feed under https://www.siemens.com/cert.

Installing the Device
2.2Unpacking the device
2.2 Unpacking the device
When unpacking the device, do the following:
1. Inspect the package for damage before opening it.
2. Visually inspect each item in the package for any physical damage.
3. Verify all items are included.
Note
If any item is missing or damaged, contact Siemens for assistance.
2.3 Mounting the Device
The RUGGEDCOM RSG908C 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.
Note
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
reduction 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 25).
2.3.1 Mounting the Device on a DIN Rail
The RUGGEDCOM RSG908C 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) by 15 mm (0.6 in) IEC/EN 60715 or TS35 DIN rail.
NOTICE
DIN rail mounting is not recommended for constant vibration environments.
Mounting the Device
To mount the device to a DIN rail, do the following:
1. Hook the top teeth of the adapter onto the DIN rail.

4. Secure the adapters to the panel with M5 or #10-24 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 active
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 RSG908C.
One common application for this relay is to signal an alarm if a power failure occurs.
For more information, refer to the "RUGGEDCOM ROS Configuration Manual" for the
RUGGEDCOM RSG908C.
To connect the failsafe alarm relay, do the following:
1. Insert the failsafe alarm relay terminal block into the device and tighten the
screws.
