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 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. You can find more information about industrial security by visiting:

1.4 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 Performance
(Page 39).

3.1 Basic safety notes
CAUTION
Hot surfaces resulting from hot process media
Risk of burns resulting from surface temperatures above 65 °C (149 °F).
•Take appropriate protective measures, for example contact protection.
•Make sure that protective measures do not cause the maximum permissible ambient
temperature to be exceeded. Refer to the information in Technical data (Page 38).
Note
Material compatibility
Siemens can provide you with support concerning selection of sensor components wetted by
process media. However, you are responsible for the selection of components. Siemens
accepts no liability for faults or failures resulting from incompatible materials.
WARNING
Unsuitable connecting parts
Risk of injury or poisoning.
In case of improper mounting, hot, toxic, and corrosive process media could be released at
the connections.
•Ensure that connecting parts (such as flange gaskets and bolts) are suitable for
connection and process media.
WARNING
Exceeded maximum permissible operating pressure
Risk of injury or poisoning.
The maximum permissible operating pressure depends on the device version, pressure
limit and temperature rating. The device can be damaged if the operating pressure is
exceeded. Hot, toxic and corrosive process media could be released.
Ensure that maximum permissible operating pressure of the device is not exceeded. Refer
to the information on the nameplate and/or in Technical data (Page 38).

•In installations with strong vibrations, mount the transmitter in a low vibration
environment.
NOTICE
Aggressive atmospheres
Damage to device through penetration of aggressive vapors.
•Ensure that the device is suitable for the application.
NOTICE
Direct sunlight
Device damage.
The device can overheat or materials become brittle due to UV exposure.
•Protect the device from direct sunlight.

Note
•
Correct location is the key to a successful application
•
Avoid reflective interference from vessel walls and obstructions by following the
guidelines below
Avoid central locations on vessels
For vessels with conical or parabolic tops, avoid mounting the device at the center. The
concavity of the top can focus echoes into the center, giving false readings.
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.

For pressure applications, it will be necessary to use PTFE tape or other appropriate
thread sealing compound, and to tighten the process connection beyond hand-tight.
•
There is no limit to the number of times the device can be rotated without damage.
•
When mounting, orient the front or back of the device towards the closest wall.
•
Do not rotate the enclosure after programming and device configuration, otherwise an
error may occur, caused by a polarity shift of the transmit pulse.
1. Before inserting SITRANS LR200 into its mounting connection, check to ensure the
threads are matching, to avoid damaging them.
2. Screw SITRANS LR200 into the process connection and hand tighten. For pressure
applications, it will be necessary to use PTFE tape (or other appropriate thread sealing
compound) and to tighten the process connection beyond hand tight.
The maximum torque is 40 N·m (30 ft.lbs).
