Security information
Siemens provides products and solutions with industrial security 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
security 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 security measures that may be implemented, please
visit
https://www.siemens.com/industrialsecurity (https://www.siemens.com/industrialsecurity)
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 customers’ exposure to cyber
threats.

When installing the device, keep to the safety notices listed below.
WARNING
If a device is operated in an ambient temperature of more than 50 °C, the temperature of the
device housing may be higher than 70 °C. The device must therefore be installed so that it is
only accessible to service personnel or users that are aware of the reason for restricted access
and the required safety measures at an ambient temperature higher than 50 °C.
WARNING
If the device is installed in a cabinet, the inner temperature of the cabinet corresponds to the
ambient temperature of the device.
