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

•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
