LOCATING AND GAINING ACCESS TO EQUIPMENT ELEMENTS

5.3.1

Analyzer Electrical/Electronic Units

The electrical/electronic units of the Analyzer, except for the detector and heater elements, are
located in the upper enclosure of the Analyzer and are fully accessible from the front of the unit.
Printed circuit assemblies are contained inside an explosion-proof housing, accessible by removing
a threaded cover plate from the housing front. See Figure 5-1.
SERIOUS PERSONAL INJURY OR DEATH POSSIBLE
The upper purged enclosure should not be opened when the unit is exposed to an
explosive environment. If access to the upper purged enclosure is required, precautions
must be taken to ensure that an explosive environment is not present.
Failure to observe all safety precautions could result in serious injury or death.
