2 Basic safety instructions
2.1 Requirements for personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣Personnel must be authorized by the plant owner/operator.
‣Be familiar with federal/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).
‣Personnel must follow instructions and comply with general policies.
The operating personnel must fulfill the following requirements:
‣Personnel are instructed and authorized according to the requirements of the task by
the facility's owner-operator.
‣Personnel follow the instructions in this manual.
2.2 Designated use
Application and media
The measuring device described in these Operating Instructions is intended for continuous,
non-contact level measurement in liquids. Because of its operating frequency of approx.
26 GHz, a maximum radiated pulsed power of 5.7 mW and an average power output of
0.015 mW, use outside of closed, metallic vessels is also permitted. If operated outside of
closed vessels, the device must be mounted in accordance with the instructions in the
"Installation" section. Operation of the devices does not pose a risk to health or the
environment.
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 for the following measurements only:
‣Measured process variables: distance
‣Calculated process variables: volume or mass in vessels of any shape; flow through
measuring weirs or channels (calculated from the level by 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 have
an adequate level of resistance.
‣Observe the limit values (see "Technical data").
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Verification for borderline cases:
‣With regard to special media and media used for cleaning, please contact the
manufacturer. Endress+Hauser will be happy to assist in clarifying the corrosion-
resistant properties of wetted materials but does not accept any warranty or liability.
Residual risks
Due to heat transfer from the process as well as power dissipation within the electronics,
the temperature of the electronics housing and the assemblies contained therein may rise
to 80 °C (176 °F) during operation. When in operation, the sensor can reach a temperature
close to the medium temperature.

Micropilot FMR20 MODBUS RS485 Basic safety instructions
Endress+Hauser 9
Danger of burns from contact with surfaces!
‣In the event of elevated fluid temperatures, ensure protection against contact to
prevent burns.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.
2.4 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 interference-free operation of the device.
Modifications to the device
Unauthorized modifications to the device are not permitted and can lead to unforeseeable
dangers:
‣If modifications are nevertheless required, consult with the manufacturer.
Repair
To ensure continued operational safety and reliability:
‣Carry out repairs on the device only if they are expressly permitted.
‣Observe federal/national regulations pertaining to the repair of an electrical device.
‣Use only original spare parts and accessories from the manufacturer.
Hazardous area
To eliminate the risk of danger to persons or the facility when the device is used in the
approval-related area (e.g. explosion protection, pressure equipment safety):
‣Check the nameplate to verify if the device ordered can be put to its intended use in the
approval-related area.
‣Observe the specifications in the separate supplementary documentation that is an
integral part of this manual.
2.5 Product safety
