NOTES
ApplicationsoftheVS-656RC5
Selection
■Use1:1withaninverter.DonotconnectmorethanoneinvertertooneVS-656RC5.
■UseaVS-656RC5whosecapacityisequaltooneexceedingthecapacityoftheinvertertobeconnected.
■DonotconnecttheVS-656RC5inparallelwithanotherpowerregenerativeunit.
■Whenpowerregenerationisexecutedcontinuouslyusing○＋ 3terminaloftheVS-686SS5,
setthemaximumto80%.Ifmoreregenerationisnecessary,usealargercapacityVS-656RC5
sandinverter.
Installation
■Avoidoilmistordust.Placetheinverterinacleanareaorhouseitinatotally-enclosedcasesothatno
contaminationenters.Tousethetotally-enclosedcase,selectthecoolingmethodandpaneldimensionssothe
VS-656RC5ambienttemperaturewillbewithintheallowablerange.
■DonotinstalltheVS-656RC5onflammablematerial,suchaswood.
■InstalltheVS-656RC5onawallwiththelongersideintheverticalposition.
■Donotsubjecttheinvertertohalogengases,suchasfluorine,chlorine,bromine,andiodine,atanytime
evenduringtransportationorinstallation.
Operation
■ApplyingpowertotheVS-656RC5,DOUBLECHECKWIRINGANDSEQUENCEBEFORETURNINGTHE
POWERON.
■AfterturningthepoweroftheVS-656RC5OFF,electricchargesintheinternalcapacitorsareretained
temporarily.WaituntilthechangeLEDgoesoffbeforetouchingtheinsideoftheVS-656RC5.
■UseroundpressureterminalwhenwiringULandc-ULlistedVS-656RC5.Caulkingshoudbedonebythe
caulkingtoolsspecifiedbyterminalmanufactures.
■TheVS-656RC5cannotbeusedwithasingle-phasepowersupply.Makesuretouseathree-phasepower
supply.
ApplicationsofthePeripheralDevices
■InstallationandselectionofanACreactor
Aninputthree-phasereactorcorrespondingtoeachmodelisnecessarywhenoperatingtheVS-656RC5.
Forselectionofareactor,seep.10and11.ThisinputACreactoriseffectiveagainstsaturatedcurrents
andexcessiveheat.
■Installationandselectionoffuses
Connectafuseontheprimarysideofthepowersuppressingreactor.Forselectionofafuse,seep.12.
■Installationofanoisefilter
Whenaddinganinputnoisefiltertotheinverter,connectittotheprimarysideofthepowercoordinating
reactor.
