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
necessary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mount-
ing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.
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enclosure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
Dieselenginedrivenfirepumpcontrollersshallbepoweredbyadedicatedsourceprotectedbya
fuseorcircuitbreaker.Verifythelabelonthecabinettoselectthecorrectprotection.Alwaysfol-
lowthisprocedurewhenconnectingordisconnectingthecontroller:Connectbothbatteries
beforeconnectingtheACpower.DisconnecttheACpowerbeforedisconnectingthebatteries.
DisconnectingthebatterieswhiletheACisconnectedmayresultinseveredamagetothecon-
trollerelectronicboards.
