EL3000 CONTINUOUS GAS ANALYZERS
 The cables have to be properly inserted in the screwed cable glands and
sealed by screwing the nut firmly in order to comply with degree of case
protection IP65. Cable connectors not in use have to be closed with
suitable vent plugs in order to ensure degree of case protection IP65
here as well.
 Purging gas connections not in use during operation have to be closed
with vent plugs.
 If the installation site of the gas analyzer is hazardous, the case must not
be opened live and electrical connectors must not be disconnected live.
 Due to the low mechanical stability of the display window, the gas ana-
lyzer has to be installed and operated in such a way that mechanical
damage to the display window with an energy exceeding 2 Joule is ruled
out. In the event that the display window is still damaged making it im-
possible to comply with degree of case protection IP65, the gas analyzer
has to be shut down, secured against re-starts and it has to be repaired.
 Due to the low UV resistance of the plastic parts of the housing, the gas
analyzer has to be installed and operated in such a way that exposure to
UV radiation is ruled out. In the event that the housing is still damaged
by UV radiation making it impossible to comply with degree of case
protection IP65, the gas analyzer has to be shut down, secured against
re-starts and it has to be repaired.
 The battery may not be replaced in an explosive atmosphere.
 Only the original battery may be used as replacement: Lithium button
cell battery Varta type no. 6032 (3 V CR 3032).
According to EU Directive 2014/34/EU and the general requirements for
equipment installed in explosive atmospheres stated in IEC 60079-0, the
scope of the certification of our equipment is limited to atmospheric condi-
tions, unless specified otherwise in our certificates.
Atmospheric conditions are defined as follows:
 Temperature range −20 to +60 °C
 Pressure range p = 80 to 110 kPa (0.8 to 1.1 bar)
abs
 Ambient air with normal oxygen content, typically 21 % v/v
If the atmospheric conditions are not met, the operator is obliged to ensure
the safe operation of our equipment outside the atmospheric conditions by
means of further measures (for example, assessment of the gas mixture)
and / or supplementary protection devices.
