EL3000 CONTINUOUS GAS ANALYZERS | CI/EL3000-EN REV. C 11
Special conditions
• The cables must be inserted into the cable glands properly
and gasketed by tightening the screws so that the IP 65
housing protection is maintained.
Unused cable glands must be sealed with suited sealing
plugs, so that the IP 65 housing protection is guaranteed
here as well.
• During operation, the unused purge gas connections must be
sealed with sealing plugs.
• If there is an explosion hazard at the installation site of the
gas analyzer, the housing must not be opened when live and
the connectors must not be disconnected when live.
• Due to the low mechanical stability of the viewing glass, the
gas analyzer must be designed and operated in such a way
that mechanical damage to the viewing glass with an energy
greater than 2 J can be excluded. If the viewing glass
becomes nevertheless damaged to the point that the IP 65
housing protection is no longer met, the gas analyzer must
be decommissioned, secured against recommissioning and
repaired.
• Due to the low UV resistance of the plastic parts of the
housing, the gas analyzer must be designed and operated in
such a way that the effect of UV radiation can be excluded. If
the housing is nevertheless damaged by UV radiation to the
point that the housing protection IP 65 is no longer
maintained, the gas analyzer must decommissioned, secured
against recommissioning and repaired.
Replacing the battery
• The battery may only be replaced in a non-hazardous
atmosphere.
• Only the original battery may be used as a spare: lithium
button cell 3 V type Varta CR2032.
