3. How to Install
■ Installation 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
internal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multiple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flammable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.
