3 Basic safety instructions
3.1 Requirements for personnel
The personnel must fulfill the following requirements for its tasks:
‣Trained, qualified specialists must have a relevant qualification for the specific function
and task
‣Are authorized by the plant owner/operator
‣Are familiar with federal/national regulations
‣Must have read and understood the instructions in the manual and supplementary
documentation
‣Follow instructions and comply with conditions
3.2 Intended use
Application and media
The measuring device described in this manual is intended only for the level measurement of
liquids. Depending on the version ordered, the measuring device can also measure potentially
explosive, flammable, poisonous and oxidizing media.
If the limit values specified in the "Technical data" and the conditions listed in the manual and
additional documentation are observed, the measuring device may be used for the following
measurements only:
‣Measured process variables: level
‣Calculable process variables: volume or mass in any shape of vessel (calculated from the
level by the linearization functionality)

Levelflex FMP53 HART Basic safety instructions
Endress+Hauser 5
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 in the "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-intended use.
Verification for 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 high medium 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 according to federal/national
regulations.
With divisible probe rods, medium may penetrate the joints between the individual parts of
the rod. This medium may escape when the joints are loosened. This can cause injuries in the
case of dangerous (e.g., aggressive or toxic) media.
‣When loosening the joints between the individual parts of the probe rod, wear appropriate
protective equipment according to the medium.
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 the 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.

Incoming acceptance and product identification Levelflex FMP53 HART
6 Endress+Hauser
‣Use only original spare parts and accessories from the manufacturer.
Hazardous area
To eliminate danger to persons or the installation when the device is used in the hazardous
area (e.g. explosion protection, pressure vessel safety):
‣Check the nameplate to verify whether the ordered device can be put to its intended use in
the hazardous area.
‣Observe the specifications in the separate supplementary documentation, which is an
integral part of this manual.
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.
NOTICE
Loss of degree of protection by opening of the device in humid environments
‣If the device is opened in a humid environment, the degree of protection indicated on the
nameplate is no longer valid. This may also impair the safe operation of the device.
3.5.1 CE mark
The measuring system meets the legal requirements of the applicable EU directives. These are
listed in the corresponding EU Declaration of Conformity together with the standards applied.
The manufacturer confirms successful testing of the device by affixing to it the CE mark.
3.5.2 EAC conformity
The measuring system meets the legal requirements of the applicable EAC guidelines. These
are listed in the corresponding EAC Declaration of Conformity along with the standards
applied.
The manufacturer confirms successful testing of the device by affixing to it the EAC mark.

LCAUTION
To ensure electrical safety:
‣Do not disconnect the protective ground connection.
‣Disconnect the device from the supply voltage before disconnecting the protective ground.
Connect protective ground to the inner ground terminal (3) before connecting the supply
voltage. If necessary, connect the potential matching line to the outer ground terminal.
In order to ensure electromagnetic compatibility (EMC): do not ground the device
exclusively via the protective ground conductor of the supply cable. Instead, the
functional grounding must also be connected to the process connection (flange or
threaded connection) or to the external ground terminal.
An easily accessible power switch must be installed in the proximity of the device. The
power switch must be marked as a disconnector for the device (IEC/EN61010).
