Overview
About This Document
This document describes the essential health and safety (EH&S) requirements
for the 993X Gas Analyzer intended for use in Class I, Division 2, and ATEX/
IECEx Zone 2 environments.
References to 993X in this document refer to derivative models of this
analyzer, where ‘X’ can be an alphanumeric character such as 0–9,
a–z, or A–Z (example, 9931, 9932, 9933, or 9934).
The procedures and information discussed in this document include only the
steps to install, operate, and prepare for servicing the 993X Analyzer. They do,
however, include all relevant safety warnings and cautions to ensure the safety
of personnel and the analyzer in explosive atmosphere locations.
AMETEK takes great eort to ensure that its translations of docu-
ments into foreign languages are accurate and complete. However,
in the case of any discrepancies between the English version and the
translated version, the original English version shall take precedence.
AMETEK will not assume liability for any such discrepancies, or issues
arising from them.

Important Safety Information
This section describes important safety information to avoid personal injury
and damage to the equipment while installing, operating, maintaining, or ser-
vicing the equipment. All safety regulations, standards, and procedures at the
analyzer location must be followed.
All personnel involved with the installation, start-up, operation, maintenance,
service, and/or troubleshooting of the analyzer – and before opening it at any
time after it has been in operation – must review and follow all Warnings, Cau-
tions, and Notes in this document. This information contains important safety
and general information about the analyzer.
WARNINGS, CAUTIONS, and NOTES contained in this manual emphasize critical
instructions as follows:
An operating procedure which, if not strictly observed, may result in
personal injury or environmental contamination.
An operating procedure which, if not strictly observed, may result in
damage to the equipment.
Important information that should not be overlooked.
Burn hazard. Hot surface. Do not touch, allow to cool before servicing.

Warnings, Cautions, Notes
Before installing, operating, and performing any maintenance,
service, and/or troubleshooting on the analyzer, read and follow all
safety information in this document (and in the analyzer User Manu-
al). Misuse of this product could result in personal injury and/or dam-
age to the equipment or its installation site. All regulatory agency
and personnel safety procedures for your jurisdiction must be
followed.
All covers and doors must be tightly fastened with all screws or latches
and the Measuring Cell and Optical Bench Assemblies must remain in
place while the circuits are live.
If installed in a hazardous classied area and it is necessary to open
the analyzer’s covers or doors while the circuits are live, rst test the
area for ammable gases and proceed only when the area is safe.
When the Electronics Enclosure’s door is open, take appropriate
precautions to avoid electrical shock. Hazardous voltages are present
inside.
Always disconnect AC mains power and/or alternate power sources
(example, for relay contacts) to the analyzer before opening any
covers or doors on the analyzer, before making any wiring or cable
connections, and before removing any sample system assemblies and
components from the analyzer.
All electrical connections, adjustments, or servicing of the analyzer
must be performed only by properly trained and qualied personnel.
All electrical connections, materials, and methods (plus all safety poli-
cies and procedures) must be made in compliance with local wiring
regulations and electrical codes for the hazardous area, as specied
by the Owner Company, local electrical-inspection authority, and
National/EU regulations.
EH&S |3

PN 903-8820, Rev A
Because ultraviolet (UV) radiation can harm your eyes, never view the
light emanating through the end window of the hollow cathode lamp.
If the source lamp must be viewed while energized, wear UV coated
safety glasses that block UV radiation.
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
eld 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 discharge static electric-
ity buildup on yourself) before, and handle/touch the boards only by
their edges, to avoid touching any of their components.
The electronic circuit boards and other static-sensitive components
should be stored and transported in static-shielding carriers or pack-
ages.
For electric-shock protection, the analyzer must be operated from a
grounded power source that has a securely connected protective-
ground contact.

These symbols may appear on the instrument to alert you of existing condi-
tions.

Electrical Safety
High voltages are present inside the Electronics Enclosure. Always shut down
power source(s) before performing maintenance or troubleshooting. Only a
qualied electrician should make electrical connections and ground checks.
Any use of the equipment in a manner not specied by the manufacturer may
impair the safety protection originally provided by the equipment.
Grounding
Instrument grounding is mandatory. Performance specications and
safety protection are void if instrument is operated from an improp-
erly grounded power source.
Verify ground continuity of all equipment before applying power.

UV Source Lamps Disposal
AMETEK recommends that all UV lamps – whether they are new, used, or dam-
aged in any way – need to be disposed of in an environmentally safe manner.
Most UV lamps do not contain restricted substances listed under European
RoHS 2 Directives. However, special handling requirements are required for
some lamps if they are broken. Two examples include Cadmium and Beryllium
lamps.
