2.2 SelectingtheInstallation
Location
Thetransmitterisdesignedtowithstandsevere
environmentalconditions.However,toensurethatitwill
provideyearsofstableandaccurateperformance,take
thefollowingprecautionswhenselectingtheinstallation
location.
(a)AmbientTemperature
Avoidlocationssubjecttowidetemperaturevariations
orasignicanttemperaturegradient.Ifthelocationis
exposedtoradiantheatfromplantequipment,provide
adequatethermalinsulationand/orventilation.
(b)AmbientAtmosphere
 Donotinstallthetransmitterinacorrosive
atmosphere.Ifthiscannotbeavoided,theremustbe
adequateventilationaswellasmeasurestoprevent
theleakingofrainwaterandthepresenceofstanding
waterintheconduits.
(c)ShockandVibration
 Althoughthetransmitterisdesignedtoberelatively
resistanttoshockandvibration,aninstallationsite
shouldbeselectedwherethisiskepttoaminimum.
(d)InstallationofExplosion-protectedTransmitters
 Anexplosion-protectedtransmittersiscertiedfor
installationinahazardousareacontainingspecic
gastypes.Seesubsection2.4“Installationofan
Explosion-ProtectedInstrument.”
2.3 PressureConnection
WARNING 
• Neverloosentheprocessconnectorboltswhenan
instrumentisinstalledinaprocess.Thedeviceis
underpressure,andalossofsealcanresultina
suddenanduncontrolledreleaseofprocessuid.
• Whendrainingtoxicprocessuidsthathave
condensedinsidethepressuredetector,take
appropriatestepstopreventthecontactofsuch
uidswiththeskinoreyesandtheinhalationof
vaporsfromtheseuids.
Thefollowingprecautionsmustbeobservedinorderto
safelyoperatethetransmitterunderpressure.
(a)Makesurethattheprocessconnectorboltsare
tightenedrmly.
(b)Makesurethattherearenoleaksintheimpulse
piping.
(c) Neverapplyapressurehigherthanthespecied
maximumworkingpressure.

Ifacustomermakesarepairormodicationtoan
intrinsicallysafeorexplosionproofinstrumentandthe
instrumentisnotrestoredtoitsoriginalcondition,its
intrinsicallysafeorexplosionproofconstructionmaybe
compromisedandtheinstrumentmaybehazardousto
operate.PleasecontactYokogawabeforemakingany
repairormodicationtoaninstrument.
CAUTION
Thisinstrumenthasbeentestedandcertiedas
beingintrinsicallysafeorexplosionproof.Please
notethatsevererestrictionsapplytothisinstrument’s
construction,installation,externalwiring,maintenance
andrepair.Afailuretoabidebytheserestrictionscould
maketheinstrumentahazardtooperate.
WARNING 
Maintainingthesafetyofexplosionproofequipment
requiresgreatcareduringmounting,wiring,and
piping.Safetyrequirementsalsoplacerestrictionson
maintenanceandrepair.Pleasereadthefollowing
sectionsverycarefully.

appliedtothediaphragmseals.
• Exercisecaresoasnottodamagediaphragm
