Legal information
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.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

1.3 Security information
SITRANS LUT400
Operating Instructions, 07/2019, A5E33329501-AC 15
1.3 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
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.

Operating Instructions, 07/2019, A5E33329501-AC 17
2.2 FCC Conformity
US Installations only: Federal Communications Commission (FCC) rules
Note
Void user authority
Changes or modifications not expressly approved by Siemens could void the user’s authority
to operate the equipment.
Note
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful i
nterference when the equipment is operated in a
commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference to radio communications, in which case the user will be required to correct the
interference at his own expense.
2.2.1 CE Electromagnetic Compatibility (EMC) Conformity
This equipment has been tested and found to comply with the following EMC Standards:

Note
Operation under special atmospheric conditions
Ultrasonic measurement requires that the sound wave travel through the atmosphere in a
consistent manner. Applications with atmospheric conditions different from air (including, but
not limited to gas layer stratification, very high
methane or CO2concentrations), should be
properly assessed to ensure safe reliable use in the event of measurement errors due to
sound wave velocity changes. Please contact your local Siemens representative for
assistance.
