CAUTION!
•ForCEcompliance,aproperlygroundedshieldingcableis
required.
•Usecopperwireonly.Insulateorwirenutallunusedleads.
•Supplyaseparatecableforrelayandsignaloutwhenusingline
voltagetopowertherelay.
•Anywiringmaycarrythefulloperanglinevoltagecurrentbased
oneldinstallaon.Thecoverlockingscrewmustbeinstalledif
thelinevoltageissuppliedtotherelay.
•Careshouldbeusedtoavoidelectrostacdischargetothedevice.
•Thisunithasconguraonjumpers.Youmayneedtorecongure
thisdeviceforyourapplicaon.
1)Routethecablesthroughthesquareopeninginthebackplateor
forsurfacewiringselectaknockoutonthetoporboomofthe
wallplate,asshowninFigure2a.
2)ConnectthewiresasshowninFigure2band2c.
