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.

1.5 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.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under

packaged to provide sufficient protection during transport. Siemens cannot assume liability
for any costs associated with transportation damages.
NOTICE
Insufficient protection during storage
The packaging only provides limited protection against moisture and infiltration.
● Provide additional packaging as necessary.
Special conditions for storage and transportation of the device are listed in Technical data
(Page 41).
The contents of this manual shall not become part of or modify any prior or existing agreement,
commitment or legal relationship. The sales contract contains all obligations on the part of
Siemens as well as the complete and solely applicable warranty conditions. Any statements
regarding device versions described in the manual do not create new warranties or modify the
existing warranty.
The content reflects the technical status at the time of publishing. Siemens reserves the right

from the device. Always keep the information and symbols in a completely legible state.
Symbol Explanation
Consult operating instructions
Observe the safety rules, provisions and laws applicable in your country during connection,
assembly and operation. These include, for example:
● National Electrical Code (NEC - NFPA 70) (USA)
● Canadian Electrical Code (CEC) (Canada)
Further provisions for hazardous area applications are for example:
● IEC 60079-14 (international)

Loss of explosion protection
Risk of explosion in hazardous areas if the device is open or not properly closed.
● Close the device as described in Technical data (Page 41).
CAUTION
External stresses and loads
Damage to device by severe external stresses and loads (e.g. thermal expansion or pipe
tension). Process media can be released.
● Prevent severe external stresses and loads from acting on the device.

3.1.2 Installation location requirements
CAUTION
Strong vibrations
Damage to device
● In plants with strong vibrations, mount the transmitter in a low vibration environment away
from the sensor.
NOTICE
Aggressive atmospheres
Damage to device through penetration of aggressive vapors.
● Ensure that the device is suitable for the application.
NOTICE
Direct sunlight
Damage to device.
The device can overheat or materials become brittle due to UV exposure.
● Protect the device from direct sunlight.
● Make sure that the maximum permissible ambient temperature is not exceeded. Refer to
the information in Installing/mounting (Page 17).
WARNING
Insufficient air circulation
Risk of fire.
The device may overheat or start burning in case of insufficient air circulation.
● Ensure sufficient air circulation in the room. Refer to the information in Technical data
(Page 41).

3.1.3 Proper mounting
NOTICE
Incorrect mounting
The device can be damaged, destroyed, or its functionality impaired through improper
mounting.
● Before installing ensure there is no visible damage to the device.
● Make sure that process connectors are clean, and suitable gaskets and glands are used.
● Mount the device using suitable tools. Refer to the information in Technical data
(Page 41).
3.2 Sensor installation
CAUTION
Electromagnetic fields
Do not install the flowmeter in the vicinity of strong electromagnetic fields, for example near
motors, variable frequency drives, transformers etc.
Upstream / downstream
● No pipe run requirements, that is straight inlet/outlet sections, are necessary.
● Avoid long drop lines downstream from the sensor to prevent process media separation
causing air / vapor bubbles in the tube (min. back pressure: 0.2 bar).
● Avoid installing the flowmeter immediately upstream of a free discharge in a drop line.
