Warning notice system

This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage

to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices

referring only to property damage have no safety alert symbol. These notices shown below are graded according to

the degree of danger.

DANGER

indicates that death or severe personal injury will result if proper precautions are not taken.

WARNING

indicates that death or severe personal injury may result if proper precautions are not taken.

CAUTION

indicates that minor personal injury can result if proper precautions are not taken.

NOTICE

indicates that property damage can result if proper precautions are not taken.

If more than one degree of danger is present, the warning notice representing the highest degree of danger will be

used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property

damage.

Quali󹪝ed Personnel

The product/system described in this documentation may be operated only by personnel quali󹪝ed for the speci󹪝c

task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

Quali󹪝ed personnel are those who, based on their training and experience, are capable of identifying risks and

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. 󹪝rewalls 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 customer’s exposure to cyber

threats.
