MODEL 1000 SEP 2005
INSTALLATION AND SETUP
3-5
Follow these precautions if installing or operating the Model 1000 Analyzer instrumentation
in a hazardous area:
(1) Install and operate only the purged version of the GC Controller in a hazardous area.
(2) Do not operate in a hazardous area any printer or personal computer (PC) that is connected
to the GC Controller. To interface with a GC Controller in a hazardous area, use the
Controller's keyboard and liquid crystal display (LCD) that are built into the purged housing
as options. Or, alternatively, use a PC that is located in a nonhazardous area and remotely
connected to the GC Controller.
(3) Ensure that field connections to the Analyzer and the GC Controller are made through purged
conduit or flameproof glands.
EQUIPMENT DAMAGE OR PERSONAL INJURY
Observe ALL applicable regulations when installing purged GC units.
Failure to observe all regulations when installing purged GC units may result in
noncompliance, equipment damage or personal injury.
The purged GC Controller and Analyzer housings are certified for use in locations where fire and
explosion hazards may exist, specifically, areas that are classified by the National Electronics Code
(NEC) as Class I, Division 1, Groups C and D. However, other regulations apply. For example, all
interconnecting runs of cable through conduit must be sealed at least 18 inches beyond the conduit's
point of entry into certified purged housing. Consult your company's policies and procedures and
other applicable requirements documents to determine appropriate wiring and installation practices.
