All analyzers bearing the CE Mark imprint on their nameplates have electromagnetic
compatibility (EMC) shielding that meets the requirements for CE Marking. When
working with one of these analyzers, you must handle it carefully to avoid damaging
the shielding. If any shielding becomes damaged or is removed from the analyzer,
new shielding must be installed to maintain the CE Marking conformity.
ABB Lewisburg has designed "Total Envelope Protection" into its analyzers. The
basic enclosure itself, when it is properly "grounded" or "earthed", becomes the first
barrier of protection from emissions that could radiate from the unit. In addition, the
enclosure also provides a high level of immunity from electromagnetic interference
(EMI) which could affect the performance of the analyzer.
In order for the analyzers produced by ABB Lewisburg to maintain their EMC
integrity, the installation methods employed are of equal importance. The grounded
enclosure produces a Faraday Shield around the electronic components, detection
systems, and other sensitive components which could generate EMI or be affected by
EMI. An extension of this Faraday shield must be carried throughout the installation
scheme.
Special conditions of Certificate of Conformity LCIE 02 ATEX 6025 X apply to the
electrical equipment for its safe use. Special conditions for electrical and purge and
pressurization are included on the nameplate of the analyzer. In addition, a multi-
lingual safety manual listing these special conditions is included with the shipment of
each analyzer. Special conditions for manufactured Ex components, which are
described in the individual subsections of Section 8 ("REPAIR") of this manual, apply
to the following certified components:
