3 Basic safety instructions
3.1 Requirements for the personnel
Personnel must meet the following requirements to perform their tasks:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣Personnel must be authorized by the plant owner/operator.
‣They must be familiar with national regulations.
‣Before starting work, personnel must read and understand the instructions in the manual
and supplementary documentation as well as the certificates (depending on the
application).
‣They must follow instructions and comply with general policies.
3.2 Intended use
Application and media
The measuring device described in these Operating Instructions is intended for continuous,
non-contact level measurement primarily in bulk solids. Because of its operating frequency of
approx. 26 GHz, a maximum radiated pulsed power of 23.3 mW and an average power output
of 0.076 mW, the device can also be used without restrictions outside closed metal vessels
(for example, above basins, open channels or heaps). Operation is completely harmless to
humans and animals.
If the limit values specified in the "Technical data" and the conditions listed in the instructions
and additional documentation are observed, the measuring device may be used only for the
following measurements:
‣Measured process variables: level, distance, signal strength
‣Calculated process variables: volume or mass in vessels of any shape; flow rate through
measuring weirs or channels (calculated based on the level using the linearization
functionality)

To ensure that the measuring device remains in proper condition for the operation time:
‣Use the measuring device only for media to which the process-wetted materials are
sufficiently resistant.
‣Observe the limit values in the "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by using the device incorrectly or for
purposes for which it was not intended.
Clarification in the case of borderline cases:
‣For special fluids and fluids for cleaning, Endress+Hauser is glad to provide assistance in
verifying the corrosion resistance of fluid-wetted materials, but does not accept any
warranty or liability.
Residual risks
Due to heat transfer from the process as well as power loss in the electronics, the temperature
of the electronics housing and the assemblies contained therein (e.g. display module, main
electronics module and I/O electronics module) may rise up to 80 °C (176 °F). When in
operation, the sensor may reach a temperature close to the medium temperature.
Danger of burns from contact with surfaces!
‣In the event of elevated fluid temperatures, ensure protection against contact to prevent
burns.
3.3 Workplace safety
When working on and with the device:
‣Wear the required personal protective equipment as per national regulations.
3.4 Operational safety
Risk of injury!
‣Operate the device only if it is in proper technical condition, free from errors and faults.
‣The operator is responsible for ensuring trouble-free operation of the device.
Hazardous area
To eliminate danger to persons or the facility when the device is used in the hazardous area
(e.g. explosion protection):
‣Check the nameplate to verify if the device ordered can be put to its intended use in the
hazardous area.
‣Observe the specifications in the separate supplementary documentation that is an integral
part of these instructions.
3.5 Product safety
This measuring device is designed in accordance with good engineering practice to meet state-
of-the-art safety requirements, has been tested, and left the factory in a condition in which it
is safe to operate. It meets the general safety standards and legal requirements.
