WARNING
l
Power Supply
Ensure that the instrument’s supply voltage matches the voltage
of the power supply before turning ON the power.
lDo Not Use in an Explosive Atmosphere
Do not operate the instrument in locations with combustible
or explosive gases or steam. Operation in such environments
constitutes an extreme safety hazard. Use of the instrument in
environments with high concentrations of corrosive gas (H2S,
SOX, etc.) for extended periods of time may cause a failure.
lDo Not Remove Internal Unit
The internal unit should not be removed by anyone other than
YOKOGAWA's service personnel. There are dangerous high
voltage parts inside. Additionally, do not replace the fuse by
yourself.
lDamage to the Protective Construction
Operation of the instrument in a manner not specified in the
operation guide may damage its protective construction.
CAUTION
This instrument is an EMC class A product. In a domestic environ-
ment this product may cause radio interference in which case the
user needs to take adequate measures.

3. How to Install
nInstallation Location
Theinstrumentshould be installed in indoor locations meeting the following
conditions:
• Instrumented panel
 Thisinstrument isdesignedtobemountedinaninstrumentedpanel.Mount the
instrumentinalocationwhereitsterminalswillnotinadvertentlybetouched.
• Well ventilated locations
 Mounttheinstrumentinwellventilatedlocationstopreventtheinstrument’sinter-
naltemperaturefromrising.
 However,makesurethattheterminalportionsarenotexposedtowind.Exposure
to wind may cause the temperature sensor accuracy to deteriorate. To mount mul-
tipleindicatingcontrollers,seetheexternaldimensions/panelcutoutdimensions
which follow.
Ifmounting otherinstrumentsadjacenttotheinstrument,complywith
thesepanelcutoutdimensionstoprovidesufcientclearancebetweentheinstruments.
• Locations with little mechanical vibration
 Installtheinstrumentinalocationsubjecttolittlemechanicalvibration.
• Horizontal location
 Mounttheinstrumenthorizontallyandensurethatitislevel,withnoinclinationto
therightorleft.
Front panel

Note
Ifthe instrumentismovedfromalocationwithlowtemperatureand lowhumidity
toa place with high temperatureandhighhumidity,orifthetemperaturechanges
rapidly,condensationwillresult.Moreover,inthecaseofthermocouple inputs,
measurementerrorswillresult.Toavoidsuchasituation,leavetheinstrumentinthe
newenvironmentunderambientconditionsformorethan1hourpriortousingit.
Donotmounttheinstrumentinthefollowinglocations:
• Outdoors
• Locations subject to direct sunlight or close to a heater
 Installtheinstrumentinalocationwithstabletemperaturesthatremainclosetoan
averagetemperatureof23°C.Donotmountitinlocationssubjecttodirectsunlight
orclosetoaheater.Doingsoadverselyaffectstheinstrument.
• Locations with substantial amounts of oily fumes, steam, moisture, dust, or
corrosive gases
 Thepresenceofoilyfumes,steam,moisture,dust,orcorrosivegasesadversely
affectstheinstrument.Donotmounttheinstrumentinlocationssubjecttoanyof
thesesubstances.
• Areasnearelectromagneticeldgeneratingsources
 Donotplacemagnetsortoolsthatgeneratemagnetismneartheinstrument.Ifthe
instrumentis usedinlocationsclosetoastrongelectromagneticeldgenerating
source,themagneticeldmaycausemeasurementerrors.
• Locationswherethedisplayisdifculttosee
 Theinstrument uses an LCDforthedisplayunit,andthiscanbedifculttosee
fromextremelyobliqueangles.Mounttheinstrumentinalocationwhereitcanbe
seenasmuchaspossiblefromthefront.
• Areasclosetoammablearticles
 Absolutelydonot place the instrument directlyonam-
mablesurfaces.Ifsuch a circumstance is unavoidable
andtheinstrumentmustbeplacedclosetoaammable
item,provideashieldforitmadeof1.43mmthickplated
steel or 1.6 mm thick unplated steel with a space of at
least150mmbetweenitandtheinstrumentonthetop,
bottom,andsides.
• Areas subject to being splashed with water
WARNING
Be sure to turn OFF the power supply to the controller before in-
stalling it on the panel to avoid an electric shock.

5. How to Connect Wires
WARNING
• Wiring work must be carried out by a person with basic electrical
knowledge and practical experience.
• Be sure to turn OFF the power supply to the controller before
wiring to avoid an electric shock. Use a tester or similar device
to ensure that no power is being supplied to a cable to be
connected.
• For the wiring cable, the temperature rating is 75 °C or more.
• As a safety measure, always install a circuit breaker (an IEC
60947-compatible product, 5 A, 100 V or 220 V AC) in an easily
accessible location near the instrument. Moreover, provide
indication that the switch is a device for turning off the power to
the instrument.
• Install the power cable keeping a distance of more than 1 cm
from other signal wires.
• The power cable is required to meet the IEC standards concerned
or the requirements of the area in which the instrument is being
installed.
• Wiring should be installed to conform to NEC (National Electrical
Code: ANSI/NFPA-70) or the wiring construction standards in
countries or regions where wiring will be installed.
• Since the insulation provided to each relay output terminal is
Functional insulation, provide Reinforced insulation to the
external of the device as necessary. (Refer to the drawing below.)

CAUTION
• When connecting two or more crimp-on terminal lugs to the
single terminal block, bend the crimp-on terminal lugs before
tightening the screw.
• Note that the wiring of two or more crimp-on terminal lugs to the
single high-voltage terminal of the power supply and relay, etc.
does not comply with the safety standard.
CAUTION
• Provide electricity from a single-phase power supply. If the
power is noisy, install an isolation transformer on the primary
side, and use a line filter on the secondary side. When measures
against noise are taken, do not install the primary and secondary
power cables close to each other.
• If there is a risk of external lightning surges, use a lightning
arrester etc.
• For TC input, use shielded compensating lead wires for wiring.
For RTD input, use shielded wires that have low conductor
resistance and cause no significant differences in resistance
between the three wires.
• Since the limit control output relay has a life span (resistance
load of 100,000 times), use the auxiliary relay to perform ON/OFF
control.
• The use of inductance (L) loads such as auxiliary relays, motors
and solenoid valves causes malfunction or relay failure; always
insert a CR filter for use with alternating current or a diode for
use with direct current, as a spark-removal surge suppression
circuit, into the line in parallel with the load.
• After completing the wiring, the terminal cover is recommended
to use for the instrument.

• Do not use an unassigned terminal as the relay terminal.
Do not use a 100-240 V AC power supply for the 24 V AC/DC
