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.

Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.

Introduction
1.8 Transportation and storage
SITRANS F Ultrasonic flowmeters FST030 (Modbus)
Operating Instructions, 08/2017, A5E37367739-AC 13
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:
http://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply 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
http://www.siemens.com/industrialsecurity.
1.8
Transportation and storage
To guarantee sufficient protection during transport and storage, observe the following:
●Keep the original packaging for subsequent transportation.
●Devices/replacement parts should be returned in their original packaging.
●If the original packaging is no longer available, ensure that all shipments are properly
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 115).
CAUTION
Protection of transmitter parts
The styrofoam parts in the transmitter are NOT packaging material.
•Do not remove styrofoam parts.

reasonable protection against harmful interference 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 operating instructions, 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.

2.3
Requirements for special applications
Due to the large number of possible applications, each detail of the described device
versions for each possible scenario during commissioning, operation, maintenance or
operation in systems cannot be considered in the instructions. If you need additional
information not covered by these instructions, contact your local Siemens office or company
representative.
Note
Operation under special ambient conditions
We highly recommend that you contact your Siemens representative or our application
department before you operate the device under special ambient conditions as c
an be
encountered in nuclear power plants or when the device is used for research and
development purposes.
2.4
Use in hazardous areas
Qualified personnel for hazardous area applications
Persons who install, connect, commission, operate, and service the device in a hazardous
area must have the following specific qualifications:
●They are authorized, trained or instructed in operating and maintaining devices and
systems according to the safety regulations for electrical circuits, high pressures,
aggressive, and hazardous media.
●They are authorized, trained, or instructed in carrying out work on electrical circuits for
hazardous systems.
●They are trained or instructed in maintenance and use of appropriate safety equipment
according to the pertinent safety regulations.

18 Operating Instructions, 08/2017, A5E37367739-AC
2.4.1
Use in hazardous areas
WARNING
Use in hazardous areas
Risk of explosion. May cause death or serious injury.
•Only use equipment that is approved for use in the intended hazardous area and
labelled accordingly.
2.4.2
Loss of safety of device with type of protection "Intrinsic safety Ex i"
WARNING
Loss of safety of device with type of protection "Intrinsic safety Ex i"
Risk of explosion May cause death or serious injury.
If the device has already been operated in non-intrinsically safe circuits or the electrical
specifications have not been observed, the safety of the device is no longer ensur
ed for use
in hazardous areas. There is a risk of explosion.
•Connect the device with type of protection "Intrinsic safety" solely to an intrinsically safe
circuit.
•Observe the specifications for the electrical data on the certificate and/or in Technical
data (Page 115).
Special conditions for safe use
In general, it is required that:
●The terminal space may be opened when an explosive gas or dust atmosphere may be
present at any time. Access power terminals by lifting the cover only when de-energized.
●Appropriate cable connectors are used.
●Substitution of components may impair Intrinsic Safety.
●Sensor and transmitter are connected to the potential equalization throughout the
hazardous area.
●EN/IEC 60079-14 is considered for installation in hazardous areas.
Must be installed in accordance with Siemens control drawing A5E32778336A
