Potential Risks
Affecting Personnel
This section addresses the appropriate actions to undertake when faced with
hazardous situations during or before service of the analyzer. It is not possi-
ble to list all potential hazards within this document. The user is responsible
for identifying and mitigating any potential hazards present when servicing
the analyzer.

XA02708C J22 TDLAS Gas Analyzer
6 Endress+Hauser
Technicians are expected to be trained and
follow all safety protocols that have been
established by the customer in accordance
with the area hazard classification to service
or operate the analyzer. This may include, but
is not limited to, toxic and flammable gas
monitoring protocols, lockout/tagout
procedures, the use of personal protective
equipment (PPE) requirements, hot work
permits and other precautions that address
safety concerns related to the use and
operation of process equipment located in
hazardous areas.
Electrocution hazard
1. Shut off power at the main disconnect external to the analyzer.
Complete this action before performing any
service that requires working near the main
input power or disconnecting any wiring or other
electrical components.
2. 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).
Laser safety
The J22 TDLAS Gas Analyzer is a Class 1 laser product, which poses no threat
to equipment operators. The laser internal to the analyzer controller is clas-
sified Class 3R and could cause eye damage if the beam is viewed directly.
Before servicing, shut off all power to the
analyzer.

Electrostatic discharge
The coating and the adhesive label is non-conducting and may generate an
ignition capable level of electrostatic discharge under certain extreme condi-
tions. The user should ensure that the equipment is not installed in a location
where it may be subjected to external conditions, such as high pressure
steam, which may cause a build-up of electrostatic charges on non-conduct-
ing surfaces. To clean the equipment, use only a damp cloth.
Chemical compatibility
Never use vinyl acetate or acetone or other organic solvents to clean the ana-
lyzer housing or labels.

3 Equipment Installation
The safety of the analyzer is the responsibility of the installer
and the organization he/she represents.
Use appropriate protective safety equipment as recommended by local safety
codes and practices (e.g., hard hat, steel-toe shoes, gloves, etc.) and exercise
caution particularly when installing equipment at a height (i.e., one (1)
meter above ground).
Required Hardware/
Tools
• Mounting hardware (e.g., spring nuts, machine screws and nuts to fit
the size of the mounting hole)
Mounting hardware used for wall-mounting the
J22 must be able to support four times the
weight of the approximately 19 kg (40 lbs) to 43
kg (95 lbs) depending on configuration).
• Stainless steel tubing (electro-polished seamless stainless steel tubing,
6 mm [1/4 in.] O.D. x 0.1 mm [0.035 in.] wall thickness is recom-
mended, depending on configuration.)
• Stainless steel 12 mm (1/2 in.) fittings for optional enclosure purge.
Tools symbols
Lifting/Carrying the
Analyzer
The analyzer should be lifted and/or moved by a minimum of two individu-
als.
Never lift the analyzer by the controller enclosure or conduit runs, cable
glands, cables, tubing or any other part protruding through the enclosure
wall or edge of the panel or enclosure. Always carry the load using the fol-
lowing points/method shown under Mounting the Analyzer.

Mounting the
Analyzer
The J22 is manufactured for wall- or post-mount installations. Refer to the
layout diagrams mounting dimensions and additional instructions in the
Operator’s Manual.
Mounting hardware used for mounting the J22 TDLAS Gas
Analyzer must be able to support four times the weight of the
instrument (approximately 16 kg (36 lbs) to 43 kg (95 lbs)
depending on configuration).
The J22 analyzer is designed for operation
within the specified ambient temperature range.
Intense sun exposure in some areas may impact
the temperature inside the analyzer controller,
therefore, installing a sunshade or canopy over
the analyzer for outdoor installations in cases
where the rated temperature range could be
exceeded is recommended.
When mounting the analyzer, be sure to position
the instrument so that it is not difficult to
operate adjacent devices.
1. Install the bottom two mounting bolts to the mounting frame or wall.
Do not fully tighten the bolts. Leave approximately a 10 mm (1/4 in.)
gap to slide the analyzer mounting tabs onto the bottom bolts.
2. Lift the analyzer vertically at the points shown in the figure below.
Distribute the weight evenly among personnel to
avoid injury.

3. Lift the analyzer onto the bottom bolts and slide the slotted bottom
mounting tabs over the bolts. Allow the two bottom bolts to take the
weight of the analyzer while stabilizing in a vertical orientation.
1 Slotted tabs
4. Tilt the analyzer and push it towards the mounting frame or wall while
aligning the two top bolts.
5. While one person exerts the necessary pressure to hold the analyzer to
the frame or wall, the second person secures the two top bolts.
6. Tighten all four bolts.
Opening/Closing the
Analyzer Enclosure
Hazardous voltage and risk of electric shock. Failure to
properly ground the analyzer may create a high-voltage
shock hazard.
Protective Chassis and
Ground Connections
Before connecting any electrical signal or power, the protective and chassis
grounds must be connected.
• Protective and chassis grounds must be of equal or greater size than
any other current-carrying conductors, including the heater located in
the sample conditioning system
• Protective and chassis grounds to remain connected until all other wir-
ing is removed
• Protective grounding wire current carrying capacity must be at mini-
mum the same as the main supply
• Earth bonding/chassis ground shall be at least 6 mm2 (10 AWG)
Protective ground cable
• Analyzer: 2.1 mm2 (14 AWG)

Electrical Wiring
Requirements
Field wiring (Power and Signal) shall be
accomplished using wiring methods approved
for hazardous locations as per the Canadian
Electrical Code (CEC) Appendix J, the National
Electric Code (NEC) Article 501 or 505 and IEC
60079-14. The installer is responsible for
complying with all local installation codes. Use
copper conductors only.
For models of the J22 TDLAS Gas Analyzer with
SCS mounted within an enclosure, the inner
sheath of the supply cable for the heater circuit
shall be sheathed with thermoplastic,
thermosetting, or elastometric material. It shall
be circular and compact. Any bedding or sheath
shall be extruded. Fillers, if any, shall be
non-hygroscopic.
Wire temperature rating and torque
• -40 C to 105 C
• Terminal block screw torque: 1.2 N m (10 in-lbf)

Cable entries
After installing all interconnecting wiring or cabling, make sure any remain-
ing conduit or cable entries are plugged with certified accessories according
to the intended use of the product.
Thread lubricant must be applied on all conduit hub threaded
connections.
Using Syntheses Glep1 or equivalent lubricant on
all conduit screw thread is recommended.
Conduit seals and glands specific to the
application should be used where appropriate in
compliance with local regulations.
The user shall install a suitable equipment certified seal within
18 in. of the controller enclosure entrance. On models of the J22
TDLAS Gas Analyzer with enclosed SCS featuring an optional
heater, a suitable equipment seal shall be installed within 2 in.
of the outer enclosure wall of the heating circuit.

Cables Type
Ethernet/IP
The standard ANSI/TIA/EIA-568-B.2 Annex specifies CAT5 as the minimum
used for Ethernet/IP. CAT5e and CAT 6 are recommended.
Flow Switch Connec-
tion Requirements
The J22 TDLAS Gas Analyzer can be offered with a variable flow meter
equipped with an optional mechanical display and reed contact to measure
the volume flow of flammable and non-flammable gases.
Conditions of use
Installation shall be in accordance with the National Electric Code NFPA 70,
Article 500 to 510, ANSI/ISA-RP 12.06.01, IEC 60079-14 and Canadian
Electrical Code for Canada.
Installation:
Run shielded interconnection cable with shield connected to FM approved
associated apparatus ground.
The maximum temperature of terminals, cable glands and wires should be
greater than 60 C dependent of ambient and product temperature. The vari-
able area flow meter with coated parts shall be installed and maintained such
that the risk of electrostatic discharge is minimized.
