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.
