● 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.

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 only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines and
networks. Systems, machines and components should only be connected to the enterprise
network or the internet if and to the extent necessary and with appropriate security measures
(e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. You can find more information about industrial security by visiting:

Siemens’ products and solutions undergo continuous development to make them more secure.
Siemens strongly recommends you apply product updates as soon as available and always
use the latest product versions. Use of product versions that are no longer supported, and
failure to apply latest updates may increase customer’s exposure to cyber threats.
