INZ-TN5ZSU-E
First of all, read this “Caution on safety” carefully, and then use the analyzer in the correct way.
• The cautionary descriptions listed here contain important information about safety, so they should
always be observed. Those safety precautions are ranked in 3 levels, “DANGER,” “CAUTION” and
“PROHIBITION.”
Wrong handling may cause a dangerous situation, in which
there is a risk of death or heavy injury.
Wrong handling may invite a dangerous situation, in which
there is a possibility of medium-level trouble or slight injury or
only physical damage is predictable.
Items which must not be done are noted.
Caution on installation, re-installation and storage of gas analyzer
• This unit is not explosion-proof type. Do not use it in a place
with explosive gases to prevent explosion, re or other serious
accidents.
• Entrust the installation, movement or re-installation to a specialist
or the supplier. A poor installation may cause accidental tipover,
electric shock, re, injury, etc.
• The infrared gas analyzer is heavy. It should be installed with
utmost care. Otherwise, it may cause accident or injury due to tip
over or drop.
• For lifting the infrared gas analyzer, be sure to wear protective
gloves. Bare hands may invite an injury.
• This unit should be installed in a place which conforms to the
conditions noted in the instruction manual. Otherwise, it may
cause electric shocks, re or malfunction of the unit.
• During installation work, care should be taken to keep the unit
free from entry of cable chips or other foreign objects. Other-
wise, it may cause re, failure or malfunction of the unit.
• For discharging the exhaust gas, carry out piping up to a position
which is not easily accessible by persons so as not to adversely
affect the human body.

CAUTION

iv INZ-TN5ZSU-E
Caution on use
• If unusual smell or sound has been produced, immediately stop
the instrument. Any discharge produced may cause a re.
• Corrosion, clogging, pollution of measuring cell may occur, even
under the specied gas condition, depending on the actual gas
combination and/or the environment.
• In the low range between 0 to 200 ppm, initial drift may occur.
• Before leaving unused for a long time or restarting after left at
such a status for an extended length of time, follow the direc-
tions of each instruction manual because they are different from
normal starting or shutdown. Otherwise, the performance may
be poor and accidents or injuries may be caused.
• Do not operate the infrared gas analyzer for a long time with its
door left open. Otherwise, dust, foreign matter, etc. may stick on
internal walls, thereby causing faults.
Caution on wiring
• Entrust the wiring to a specialist or the supplier. Poor wiring
may cause shock hazard or injury.
• Make sure to perform class-D grounding. If the specied
grounding is neglected, an electric shock or malfunction may
be caused.
Caution to wiring electrician
For avoiding electric shock, re and injury, be sure to
observe the following.
• Before wiring, be sure to turn off the main power supplies. This
is required for preventing an electric shock.
• As a ground wire, use 600V-IV wire of 2 mm2 or thicker having
a sufcient dielectric strength. Use of a wrong grounding wire
may cause electric shock or malfunction.
• Input/output wires should have proper diameters meeting the
rated current of the infrared gas analyzer. If a wire which cannot
endure the rating is used, a re may occur.
• For connection to input and output terminal blocks, be sure to
use solderless terminals.
• For branching the output wires, use a terminal block.
• Be sure to fasten the input/output wires on the oor, wall, etc.
and put guards on the wires.
• Do not install the instrument near high frequency heating furnace,
electric welding machine or others which considerably disturb
the power waveforms. Do not share their power supplies
either.

INZ-TN5ZSU-E
Caution on maintenance and check
• For correct handling of calibration gas or other reference gases,
carefully read instruction manuals of standard gases beforehand.
Otherwise, carbon monoxide or other hazardous gases may
cause an intoxication particularly.
• Before maintenance or checkup, be sure to turn on the ventila-
tor in the infrared gas analyzer. If it is leaky, there is a risk of
intoxication.
• Before replacing the gas lter of the infrared gas analyzer or
maintaining the washer, close the calibration gas valve and, if
provided, the valve on the sample gas suction port. Otherwise,
intoxication or accident may occur.
• If the fuse is blown, eliminate the cause, and then replace it
with the one of the same capacity and type as before. Other-
wise, electric shock or failure may be caused.
• The door should be locked without fail and the key should be
kept so that a third party cannot take them away. Touching the
door carelessly may cause electric shock or failure.
• Do not use a replacement part other than specied by the in-
strument maker. Otherwise, adequate performance will not be
provided. Besides, an accident or failure may be caused.
• Replacement parts such as a maintenance part should be disposed
of as incombustibles. For details, follow the local ordinance.
• This equipment should be treated as an industrial waste when it
is disposed of.
Be sure to observe the following for safe operation avoiding
electric shock and injury.
• Remove the watch and other metallic objects before work.
• Do not touch the instrument with wet hands.
Caution on use
• Do not put stick or nger into the fan (top, peltier gas cooler).
You may get hurt by a turning fan.
• Do not allow metal, nger or others to touch the input/output
terminals in the instrument. Otherwise, electric shock or injury
may occur.
• Do not smoke nor use a ame near the infrared gas analyzer.
Otherwise, a re may be caused.
• Do not allow water to go into the infrared gas analyzer. Other-
wise, electric shock or re in the instrument may be caused.

Others
• If the cause of any fault cannot be determined despite reference
to the instruction manual, be sure to contact your dealer or Fuji
Electric’s technician in charge of adjustment. If the instrument is
disassembled carelessly, you may have an electric shock or injury.

INZ-TN5ZSU-E
This infrared gas analyzer (ZSU) is composed of infrared gas analyzer unit, oxygen sensor and gas sam-
pling equipment. It is capable of accurately and continuously measuring concentration of gases such as
NOx, SO2, CO, CO2 and O2 contained in the ue gas generated from a stationary source such as boiler and
dust incinerator.
The specication for measurement of CO and O2 includes the function that deals with dioxin efuent con-
trol.
The description in the manual may not exactly match your analyzer somewhere depending on your re-
quirements.
For drawings, piping system, device conguration, specications, standard accessories, spare/consumable
parts, refer to the shipping specications submitted separately.
