Safety instructions
WARNING
Risk of injury due to process conditions.
The process conditions, for example high pressures and
temperatures, toxic and aggressive measuring media, can
give rise to hazards when working on the device.
• Before working on the device, make sure that the process
conditions do not pose any hazards.
• If necessary, wear suited personal protective equipment
when working on the device.
• Depressurize and empty the device / piping, allow to cool
and purge if necessary.
WARNING
Risk of injury due to live parts!
When the housing is open, contact protection is not provided
and EMC protection is limited.
• Before opening the housing, switch off the power supply.
Use in Potentially Explosive Atmospheres
DANGER
Danger of explosion if the device is operated with the
transmitter housing or terminal box open!
While using the device in potentially explosive atmospheres
before opening the transmitter housing or the terminal box,
note the following points:
• A valid fire permit must be present.
• Make sure that no flammable or hazardous atmospheres
are present.
Note
• An additional document with Ex safety instructions is
available for measuring systems that are used in potentially
explosive atmospheres.
• Ex safety instructions are an integral part of this manual. As
a result, it is crucial that the installation guidelines and
connection values it lists are also observed.
The icon on the name plate indicates

Installation conditions
General
The following points must be observed during installation:
• The flow direction must correspond to the marking, if
present
• The maximum torque for all flange screws must be
complied with
• Secure flange screws and nuts against pipe vibration.
• The devices must be installed without mechanical tension
(torsion, bending)
• Install flange devices / wafer-type devices with plane
parallel counterflanges and use appropriate gaskets only
• Use gaskets made from a material that is compatible
with the measuring medium and measuring medium
temperature.
• Gaskets must not extend into the flow area, since
possible turbulence could influence the accuracy of the
device
• The piping may not exert any inadmissible forces or
torques on the device.
• Make sure that the temperature limits are not up-scaled
during operation of the device.
• Vacuum shocks in the piping should be avoided to
prevent damage to the liners (PTFE liner). Vacuum shocks
can destroy the device.
• Do not remove the sealing plugs in the cable glands until
you are ready to install the electrical cable
• Make sure the gaskets for the housing cover are seated
correctly. Carefully seal the cover. Tighten the cover
fittings
• The transmitter with a remote mount design must be
installed at a largely vibration-free location
• Do not expose the transmitter and sensor to direct
sunlight. Provide appropriate sun protection as necessary
If necessary, provide a suited means of sun protection.
• When installing the transmitter in a control cabinet, make
sure adequate cooling is provided
Devices with extended diagnostic functions
For devices with extended diagnostic functions different
installation conditions may be valid.
