Unintentional operating situations
High frequency radiation, e g. from a cellular phone, interferes with device functions and
can result in malfunctioning of the device.
Persons are injured and the plant is damaged.
Avoid high-frequency radiation:
• Remove radiation sources from the environment of the device.
• Switch off radiating devices.
• Reduce the radio output of radiating devices.
• Observe the information on electromagnetic compatibility (Page 97).
Electrostatic sensitive devices can be labeled with an appropriate symbol.
Electrostatic sensitive devices (ESD)
When you touch electrostatic sensitive components, you can destroy them through voltages
that are far below the human perception threshold.
If you work with components that can be destroyed by electrostatic discharge, observe the
ESD Guideline (Page 98).
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. For more information about industrial security, please visit
