INTRODUCTION
MediumVoltageElectricFirePumpcontrollersaredesignedtostartanelectricmotordrivenfirepump.
Itcaneitherstartthefirepumpmanuallythroughthelocalstartpushbuttonorautomaticallythrough
thesensingofapressuredropinthesprinklersystem.Thefirepumpcontrollerissuppliedwithapres-
suretransducer.Thefirepumpcanbestoppedmanuallywiththelocalstoppushbuttonorauto-
maticallyaftertheexpirationofafieldprogrammabletimer.

INSTALLATION
STORAGE
Ifthecontrollerisnotinstalledandenergizedimmediately,Tornatechrecommendsfollowingthe
instructionsinchapter3ofNEMAICS15.
ENVIRONMENT
MediumVoltageElectricFirePumpcontrollersareintendedtobeinstalledinlocationswhereambient
temperaturesarewithin4°Cand40°Candtherelativehumidityiscontrolledbetween5%and80%.
Optionally,thecontrollercanhaveanextendedtemperatureofupto55°Candaslowas-5°C,provided
thatthecontrollerandthepressurewaterpipesareheatedtopreventwaterfreezinganddamagingthe
electronicsandthepipingsystem.
Theyareintendedforpollutiondegree3andshallbeinstalledatanaltitudeofnomorethan2000
meters.Forabnormalinstallationenvironment,consultfactory.
ELECTROMAGNETIC COMPATIBILITY (EMC)
MediumVoltageElectricFirePumpcontrollershavebeentestedforthemoststringentconditionsfor
emissions(EnvironmentB)andimmunity(EnvironmentA),hencecontrollerscanbeinstalledineither
environment.Allcontrollersvariantssharethesameelectronicsandcomplytothosecriteriawithout
requiringadditionalmeasures.
HANDLING
TheweightofeachMediumVoltageElectricFirePumpcontrollerisindicatedonthepackinglabel.Light-
weightcontrollersdonotrequirespecialhandlinginstructions,whileheavycontrollersareequipped

LOCATION
Consult the appropriate job plans to determine the controller mounting location.
Thecontrollershallbelocatedascloseaspracticaltotheengineormotoritcontrolsandshallbewithin
sightoftheengineormotor.Thecontrollershallbelocatedorprotectedsuchthatitwillnotbedam-
agedbywaterescapingfrompumporpumpconnections.Currentcarryingpartsofthecontrollershall
benotlessthan12in.(305mm)abovethefloorlevel.
WorkingclearancesaroundcontrollershallcomplywithNFPA70,NationalElectricalCode,Article110or
C22.1,CanadianElectricalCode,Article26.302oranyapplicablelocalcodes.
ThestandardcontrollerenclosureisratedNEMAType2.Itistheinstaller’sresponsibilitytoinsurethat
eitherthestandardenclosuremeetstheambientconditionsorthatanenclosurewithanappropriate
ratinghasbeenprovided.Controllersmustbeinstalledinsideabuildingandtheyarenotdesignedfor
outsideenvironment.Thepaintcolormaychangeifthecontrollerisexposedtoultravioletraysfora
longperiodoftime.
MOUNTING
TheMediumVoltageElectricFirePumpcontrollershallbemountedinasubstantialmanneronasingle
incombustiblesupportingstructure.
FLOOR MOUNTING
Floormountedcontrollersshallbeattachedtothefloorusingallholesprovidedonthemountingfeet
withhardwaredesignedtosupporttheweightofthecontroller.Themountingfeetprovidetheneces-
sary12in.(305mm)clearanceforcurrentcarryingparts.
WALL MOUNTING
Refer to the controller dimension drawing for necessary mounting dimensions.
Thecontrolleriswallmountedbyusingatleastfour(4)wallanchors,2anchorsforthetopmounting
bracketsand2anchorsforthebottommountingbrackets.Thebracketsaredimensionallyonthesame
centerlineforeaseinmounting.Thereshouldbeaclearanceofatleast6inches(152mm)aroundthe
controllertoallowproperaircirculationaroundtheequipment.

V2024.02 9
1. Usingeitherthedimensionprintorbymeasuringthedistancebetweenthecenterlinesofthe
lowerbracketslots,transcribethisdimensionontothewall.Note:Thebottomedgeoftheenclos-
ureshouldbeaminimumof12”(305mm.)fromthefloorincasefloodingofthepumproom
occurs.
2. Drillandputanchorsintothewallforthelowermountingbrackets.
3. Markonthewall,thelocationoftheholesintheuppermountingbrackets.
4. Drillandputanchorsintowallfortheuppermountingbrackets.
5. Installboltsandwashersinloweranchors.
6. Alignholesinuppermountingbracketsandinstallboltsandwashersinanchors.
7. Shimanchorsasnecessarytoensurerearofenclosureisverticallevelandenclosureisnot
stressed.
8. Tightenallanchorbolts.
9. Checktobesureenclosuredooropenandclosesfreelyandthatenclosureislevel.
MAKING SYSTEM PRESSURE CONNECTIONS
Thecontrollerrequiresone(1)“SystemPressure”connectionfromthesystempipingtotheenclosure.
Theconnectionfitting,1/2”NPTmaleport,isprovidedontheleftexternalsideoftheenclosureforthis
purpose.RefertoNFPA20forcorrectfieldpipingprocedureofthesensinglinebetweenthepumping
systemandthecontroller.Ifadrainispresent,theconnectiontothedrainisataperedconnectionfor
plastictubing.
MAKING ELECTRICAL CONNECTIONS
TheelectricalwiringbetweenthepowersourceandthefirepumpcontrollershallmeettheNFPA20,
NFPA70NationalElectricalCodeArticle695orC22.1CanadianElectricalCode,Section32-200orany
applicablelocalcodes.Electricalwiringshallbetypicallysizedtocarryatleast125%ofthefullloadcur-
rent(FLCorFLA)ofthefirepumpmotor.
IMPORTANT PRECAUTIONS
Alicensedelectricianmustsupervisetheelectricalconnections.Thedimensiondrawingsshowthearea
suitableforincomingpowerandmotorconnections.Nootherlocationshallbeused.Onlywatertight
hubfittingsshallbeusedwhenenteringthecabinettopreservetheNEMAorIPratingofthecabinet.
The installer is responsible for adequate protection of the Medium Voltage Electric Fire Pump
controller components against metallic debris or drilling chips. Failure to do so may cause
injuries to personnel, damage the controller and subsequently void warranty.
Priortomakinganyfieldconnections
1. Opendoorofenclosureandinspectinternalcomponentsandwiringforanysignsoffrayedor
loosewiresorothervisibledamage.
2. Verifythatthecontrollerinformationiswhatisrequiredontheproject:

V2024.02 10
1. Tornatechcatalognumber
2. Motorelectricalnameplateinformationmatchescontrollerratingforvoltage,frequency,
