Prosonic S FMU90 Level Measurement HART Safety Instructions
Endress+Hauser 3
1 Safety Instructions
1.1 Designated use
The Prosonic S FMU90 is a transmitter for the ultrasonic sensors FDU90, FDU91, FDU91F,
FDU92, FDU93, FDU95 and FDU96. The sensors of the class FDU8x can be connected as well.
1.2 Installation, commissioning, operation
The Prosonic S is fail-safe and constructed to the state-of-the-art. It meets the appropriate
standards and EC directives. However, if you use it improperly or other than for its designated
use, it may pose application-specific hazards, e.g. product overflow due to incorrect installation
or configuration. Installation, electrical connection, start-up, operation and maintenance of the
measuring device must therefore be carried out exclusively by trained specialists authorised by
the system operator. Technical personnel must have read and understood these operating
instructions and must adhere to them. You may only undertake modifications or repair work to
the device when it is expressly permitted by the operating instructions.
1.3 Operational safety and process safety
• Alternative monitoring measures must be taken to ensure operational safety and process safety
during confiugration, testing and maintenance work on the device.
• The device is safely built and tested according to state-of-the-art technology and has left the
factory in perfect condition as regards technical safety. The applicable regulations and
European standards have been taken into account.
• Pay particular attention to the technical data on the nameplate.
• If the device is to be installed in an explosion hazardous area, then the specifications in the
certificate as well as all national and local regulations must be observed. The device is
accompanied by separate "Ex documentation", which is an integral part of this Operating
Instructions. The installation regulations, connection values and Safety Instructions listed in
this Ex document must be observed. The documentation number of the related Safety
Instructions is also indicated.
• If using devices for applications with safety integrity level, the separate manual on functional
safety must be observed thoroughly (→ see CD-ROM).
#Warning!
The sensors FDU83, FDU84, FDU85 and FDU86 with an ATEX, FM or CSA certificate are not
certified for connection to the FMU90 transmitter.
1.4 Return
Follow the instructions on returning the device as outlined in the Operating Instructions on the
CD-ROM provided.

2.1 Incoming acceptance, storage
2.1.1 Incoming acceptance
Check the packing and contents for any signs of damage. Check the shipment, make sure
nothing is missing and that the scope of supply matches your order.
2.1.2 Storage
Pack the measuring instrument so that is protected against impacts for storage and transport. The
original packing material provides the optimum protection for this.
The permissible storage temperature is -40 to +60 °C (-40 to +140 °F).
Safety conventions
#Warning!
A warning highlights actions or procedures which, if not performed correctly, will lead to personal injury,
a safety hazard or destruction of the instrument
"Caution!
Caution highlights actions or procedures which, if not performed correctly, may lead to personal injury or
incorrect functioning of the instrument
!Note!
A note highlights actions or procedures which, if not performed correctly, may indirectly affect operation
or may lead to an instrument response which is not planned
Explosion protection
0Device certified for use in explosion hazardous area
If the device has this symbol embossed on its name plate it can be installed in an explosion hazardous area
-Explosion hazardous area
Symbol used in drawings to indicate explosion hazardous areas. Devices located in and wiring entering
areas with the designation “explosion hazardous areas” must conform with the stated type of protection.
.Safe area (non-explosion hazardous area)
Symbol used in drawings to indicate, if necessary, non-explosion hazardous areas. Devices located in safe
areas still require a certificate if their outputs run into explosion hazardous areas

2.2 Installation
2.2.1 Installation conditions of the field housing
Weather protection
In order to avoid excessive sunlight exposure, the instrument should be mounted in a position
which is protected against direct sunlight or a protection cover should be applied.
Overvoltage protection
In order to protect the Prosonic against overvoltages (especially if mounted outdoors),
connection of an overvoltage protection is recommended.
Wall mounting
A mounting help for wall mounting is supplied. It also serves as drilling template. The mounting
help should be mounted on a flat surface and may not become distorted.
Pipe mounting
A mounting plate is available for mounting of the field housing to 1" to 2" pipes.
!Note!
For more information and details, see the Operating Instructions BA00288F, chapter
"Accessories" on the CD-ROM provided.

2.2.2 Installation conditions of the DIN-rail housing
• The DIN-rail housing must be mounted outside hazardous areas in a cabinet.
• The housing is mounted on a DIN rail EN 60715 TH 35 x 7.5 or TH 37 x 15.
• Do not install the instrument in the vicinity of high-voltage lines, motor lines, contactors or
frequency converters. The installation regulations for high-voltage lines, motor lines,
contactors or frequency converters must be observed.
• To ensure easy mounting and opening of the housing, a distance of approx. 10 mm (0.39 in)
should be kept between the instruments.
• In order to avoid interference signals, the sensor cables must not be laid parallel to high voltage
or electric power lines.
• The cables may not be laid in the proximity to frequency converters.
