7.4Precautionsforoperation
7.4.1Inputandoutputsignal.
(1) Inputandoutputterminalsareprovidedwithacover.Setthiscover,forsafety,withoutfail,after
finishofthewiringconnection.Donottouchtheterminalsduringtheoperatingcondition.
(2) Controlsignalinputisnovoltagecontact.Donotinputthevoltagesignal.Incaseofsettingan

(3) Switchingcapacityofcontroloutput(opticalMOS‑FETrelay)isDC100V,50mAorDC24V,100mA.
Anelementmustbesetonthecoiloftherelayinordertoabsorbcountervoltageattimeofswitching.
7.4.2Precautionsattimeofstartofoperation
(1) Busvoltagemustbeinputafterthevoltage(AC90to125V)isstable.Operatingfailuremayhappen
underunstablerangeofthepowerwhenincreasingthevoltage,becausethepowersourceofthisdevice
isincommonwithbus.
(2) Controlinputlatchisnotprovided,sothatitmustbealwaysshortcircuitattimeofselection.
7.4.3Precautionsduringstartofoperation
(1) Settingchangecannotbeperformedduringaction.Ifitmakesasettingchange,acinput(busand

(2) Ifautomaticisswitchedtomanualoperationduringaction.AfterOFFofautomatic,itwaits1secondor
more,andmanualisON.
(3) Pleasedonottouchequipmentduringaction.Itwillcausefailureinoperation.
7.4.4Precautionsafterfinishofsynchronizingcontrol
