Endress+Hauser
• 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 transmitter only when it is de-energized (and after a delay of at least 10 minutes following
shutdown of the power supply) or in an area free of explosive atmospheres.
• The housing may only be opened briefly. Avoid moisture and dirt penetrating during this time.
• It is not permissible to connect into the service adapter whilst the atmosphere is considered to be
explosive.
• Use of the devices is restricted to fluids against which the process-wetted materials are adequately
resistant.
• 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 20.
• Turning the transmitter housing: the transmitter may be turned in 90° increments only when it is
de-energized (observing a delay of 10 minutes after switching off the power supply). Retighten the
securing screws after turning the housing.
• Turning the local display: the screw cap has to be removed before the local display can be turned,
and this must be done with the device de-energized (and after a delay of at least 10 minutes
following shutdown of the power supply).
• The cable entries and openings not used must be sealed tight with suitable components.
• Measures must be taken to ensure that the transients of supply voltage do not exceed the maximum
nominal voltage by more than 40%.
General
The system meets the fundamental health and safety requirements for the design and construction of
devices and protective systems intended for use in potentially explosive atmospheres in accordance
with directive 94/9/EC and IEC 60079-15.
Identification
• The identification of the transmitter contains the following information:
– 0 II3G Ex nAC [L] IIC T4-T1 X (compact version)
or
– 0 II3G Ex nAC [L] IIC T4 X (remote version)
• The identification of the sensor contains the following information:
– 0 II3G Ex nL IIC T4-T1 X
"
Caution!
The installation instructions for safe application of the system must be observed (see Page 17).
