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 the following:

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
• 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. 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
• 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.
For additional information, see Extended diagnostic
functions on page 117.
