2 Basic safety instructions
2.1 Requirements concerning the staff
The staff must fulfill the following requirements for their tasks:
►Trained staff: Must have a qualification which corresponds to their function and tasks.
►Authorized by the plant operator.
►Familiar with the national regulations.
►Before starting their work: Must have read and understood all instructions in the operating
manual and supplementary documentation as well as the certificate (depending on the
application).
►Must comply with all instructions and the regulatory framework.
2.2 Designated use
2.2.1 Application and media
The Deltabar FMD72 is a differential pressure transmitter for measuring differential pressure and
level in pressurized tanks. The device has two sensor modules, which measure the operating

Deltabar FMD72 Basic safety instructions
Endress+Hauser 7
pressure (High Pressure HP and Low Pressure LP). The differential pressure/hydrostatic level is
calculated in the transmitter unit. The sensor signal is transmitted digitally. In addition, sensor
temperatures and the individual process pressures present at the respective sensor modules can
be individually evaluated and transmitted. 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 (process variables):
Measured process variables
• Pressure HP and Pressure LP
• Sensor temperature
Calculated process variables
• Differential pressure
• Level (level, volume or mass)
2.2.2 Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated 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.
2.2.3 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!
►For elevated fluid temperature, 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.
►Switch off the supply voltage before connecting the device.
2.4 Operational safety
Risk of injury!
►Operate the device in proper technical condition and fail-safe condition only.
►The operator is responsible for interference-free operation of the device.
Conversions to the device
Unauthorized modifications to the device are not permitted and can lead to unforeseeable
dangers
►If, despite this, modifications are required, consult with Endress+Hauser.

area (e.g. explosion protection, pressure vessel safety):
►Based on the nameplate, check whether the ordered device is permitted for the intended use
in the hazardous area.
►Observe the specifications in the separate supplementary documentation that is an integral
part of these Instructions.
2.5 Product safety
