Cautions

Review and follow these Cautions to avoid damaging the equipment.

The electronic circuit boards and other static-sensitive components should be stored and trans-

ported in static-shielding carriers or packages.

For electrical-shock protection, the analyzer must be operated from a grounded power source

that has a securely connected protective-ground contact.

If it becomes necessary to handle any of the electronic circuit boards, do not subject the boards

to static discharge. The ideal solution is a static-safe work area. Since such areas typically

are not available at analyzer installation sites, the use of a wrist strap connected directly to a

ground is recommended. If a wrist strap is not available, you should at the very least touch the

metal chassis (to ground yourself) before handling or touching the boards.

When handling the source lamps, it is very important not to touch the lamp windows because

residual oils from the fingers will absorb ultraviolet light. The window is the flat surface at the

end of the narrow glass tube. The lamp assembly is fragile and should be handled with care.

Purged Analyzer (Hazardous Location) Applications

M25 x 1.5, 6H cable entries are provided for Power (1 entry) and Signals (2 entries). See the

Model 9xx-Series Analyzer Type 200 Disconnect Enclosure Details drawing in Appendix A

for cable entry locations. In all cases, all unused cable entry ports must be plugged with a certi-

fied Ex d plug.

For Division 1/Zone 1 Installations, all cable entry glands (one power cable entry and two

signal cable entries) into the flameproof Disconnect Enclosure must be Ex d certified. Conduit

or cable seals that comply with the flameproof enclosure cable entry sealing requirements of the

local authority must be installed at the entries to the disconnect enclosure.

For Division 2/Zone 2 Installations that do not use the Disconnect Enclosure, use a suitable

cable entry device with a sealing ring that meets the local requirements for entries into pres-

surized enclosures.
