• Damage from pressure build-up during electric arcs in the event of a fault
If the building has not been designed correctly in terms of how it has been dimensioned,
damage can result from the pressure that can possibly build up inside.
• Dangerous electric arcs during internal faults
The devices have been designed according to the relevant IEC standards, and tested in line
with strict type-testing procedures. They were developed and manufactured so that there is
a very low probability of internal faults occurring. However, internal faults cannot be
completely ruled out.
WARNING
Dangerous electric arcs during internal faults
Defects such as damage to components, overvoltages, or loose parts, as well as exceptional
operating statuses, can cause a failure within the enclosure. This can result in an internal
electric arc. If an electric arc occurs and people are nearby, this could lead to death, serious
physical injury, and damage to property.
• Ensure that only qualified personnel perform any work that is required.
• Observe the safety and operating instructions in this documentation and labels attached to
the device for any work that is performed.
2.9 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

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.
