General warnings
• Compliance with national regulations relating to the installation, connection to the electricity supply,
commissioning and maintenance of devices in potentially explosive atmospheres is mandatory, if such
regulations exist.
• Installation, connection to the electricity supply, commissioning and maintenance of the devices must be
carried out by qualified specialists trained to work on Ex-rated devices.
• Compliance with all of the technical data of the device (see nameplate) is mandatory.
• Open the device only when it is de-energized (and after a delay of at least 10 minutes following shutdown
of the power supply).
• All seals on the transmitter housing must be checked at suitable time intervals to ensure that they are leak-
tight and they must be replaced, if necessary. When replacing the seals, use only original seals from
Hauser.
• It is not permissible to connect the service adapter whilst the atmosphere is considered to be explosive.
• Use of the devices is restricted to mediums against which the process-wetted materials are adequately
resistant.
Installation instructions
• The measuring device must only be used in the permitted temperature class.
The values of the individual temperature classes can be found in the temperature tables on Page 21.
• Turning the transmitter housing: the housing of the Ex-rated transmitter must only be turned in 90° steps
when the transmitter is de-energized (and after a delay of at least 10 minutes following shutdown of the
power supply).
• Turning the local display: the screw cap has to be removed before the local display can be turned, and this
