2 General Safety Information
This chapter reviews the general safety instruction for the TDLAS Gas Ana-
lyzer.
Intended Equipment
Use
The natural gas analyzers are intended for use as explained in the documen-
tation provided. Endress+Hauser recommends that the qualified technician
read and reference the documentation when installing, operating or having
direct contact with the TDLAS Gas Analyzer. Any use of the equipment in a
manner not specified by Endress+Hauser could lead to physical injury and
damage to the equipment.
Warning Labels Equipment labels are adhered to the TDLAS Gas Analyzer to alert the user of
potential hazards. Instructional symbols are also used in the equipment
manuals to indicate potential hazards, important information and valuable
tips, and are not labeled on the analyzer. Following are the equipment labels
and instructional symbols with associated warning and caution types to
observe when servicing the analyzer.
Safety label
A warning label is affixed to the front side of all analyzer enclosures that con-
tain sample gas. An example of the warning label is shown below.
Hazards may vary by stream composition. One or more of the following con-
ditions may apply.
The safety of the analyzer is the responsibility of the installer
and the organization represented.

Equipment labels
Flammable. Gases used in the processing of this analyzer
may be extremely flammable. Any work in a hazardous area
must be carefully controlled to avoid creating any possible
ignition sources (e.g., heat, arcing, sparking, etc.).
Toxins. Endress+Hauser analyzers measure a variety of
gases, including high-level H

S. Follow all safety protocols
governing toxic gases and potential leaks.
Inhalation. Inhaling toxic gases or fumes may cause physical
damage or death.
Technicians are expected to follow all safety protocols
established by the customer that are necessary for servicing
or operating the analyzer. This may include, but is not
limited to, lockout/tag-out procedures, toxic gas monitoring
protocols, personal protective equipment (PPE)
requirements, hot work permits and other precautions that
address safety concerns related to performing service or
operation on process equipment located in hazardous areas.

malfunction of the analyzer.
Failure to follow all directions or substitution of components
may result in explosion.
Failure to follow all directions may result in fire.
Maximum voltage and current specifications for fuses.
Technicians are expected to follow all safety protocols
established by the customer that are necessary for servicing
the analyzer. This may include, but is not limited to, lockout/
tagout procedures, toxic gas monitoring protocols, PPE
requirements, hot work permits and other precautions that
address safety concerns related to performing service on
process equipment located in hazardous areas.

Personnel Responsibility
Mitigating risks
Refer to the instructions for each situation listed below to mitigate risks.
Electrocution hazard
1. Shut off power at the main disconnect external to the analyzer.
2. Open enclosure door.
3. If service must be performed with power engaged, do the following:
a. Note any live electrical components and avoid all contact with them.
b. Only use tools with a safety rating for protection against accidental
contact with voltage up to 1000V (IEC 900, ASTF-F1505-04, VDE
0682/201).
Explosion/fire hazard
Any work in a hazardous area must be carefully controlled to avoid creating
any possible ignition sources (e.g., heat, arcing, sparking, etc.). All tools must
be appropriate for the area and hazards present. Electrical connections must
not be made or broken with power on (to avoid arcing).
The safety of the analyzer is the responsibility of the installer
and the organization he/she represents.
Complete this action before performing any service that
requires working near the main input power or
disconnecting any wiring or other electrical components.

Endress+Hauser Class I Division 2 analyzers use a non-
incendive protection method, and as such all portions of the
local installation codes apply. The maximum allowed
inductance to resistance ratio (L/R ratio) for the field wiring
interface must be less than 25 µH/Ω. The maximum total
loop capacitance shall be 0.27 microfarads.
The safety of the analyzer is the responsibility of the installer
and the organization he/she represents.

Lifting/carrying the analyzer
The SS500, SS2000, and SS3000 analyzers can be easily lifted from the pack-
aging and moved to the installation location. Take care not to lift or carry the
analyzer by the measurement cells or the cables connected at the top of the
analyzer, or damage may occur. For analyzers configured inside enclosures
and weighing more than 18 kg (approximately 40 lbs), lift the unit by the
mounting brackets using at least two individuals and distribute the weight
among personnel to avoid injury.
Configurations requiring optional accessories, e.g., probe
assemblies, with specific characteristics must meet
manufacturer specifications.
Endress+Hauser analyzers are designed for operation within
the specified ambient temperature range of -20 °C to 50 °C (-
4 °F to 122 °F). Intense sun exposure in some areas may
cause the analyzer temperature to exceed the maximum.
