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.

Qualified Personnel

The product/system described in this documentation may be operated only by

personnel qualified

for the specific

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

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

Link: (http://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.

To stay informed about product updates, subscribe to the Siemens Industrial Security RSS

Feed under

Link: (http://www.siemens.com/industrialsecurity)

Observe the following security recommendations to prevent unauthorized access to the

system.

●Evaluate your plant as a whole in terms of security. Use a cell protection concept with

suitable products.

●Keep the firmware up to date. Check regularly for security updates of the firmware and

use them.
