4.9.3 AC input contactors
note!  Thecontactorsizesmustbeselectedbasedontheconverterratedcurrent.Thesizingbasis
isthethermocurrentAC1,whichisabsorbedbytheinputduringtheratedfunctioning.
note!  Thetechnicaldataofthecontactors,asforexampleweights,dissipatedpowers,auxiliary
contactsetc.canbefoundintheappropriatedatasheets.
4.9.4 Control power protection
The115VAC/230VACcontrolpowerinput,U2&V2,fortheTPD32-EVarerequiredtobeshortcircuitprotected.
Thisprotectioncanbeprovidedbyusingstandardtimedelayfuses,orcircuitbreaker.
Thecircuitbreakerand/ortimedelayfusesmustbeselectedtosurvivetheshortcircuitavailablecurrentofthe
feedersourceforthiscircuit,andtheinrushcurrentofthedrivepowersupply.
Theratingofthefusesorcircuitbreakershouldbesizedmainlytoprotectthewiringfromthefuses/circuit
breakerconnectionstoU2&V2,andnotnuisancetriporblowfromtheinrushcurrent.
Thetablebelow,Table4.9.5,liststheinputcurrentcharacteristicsofthecontrolpower.
ForversionTPD32-EV-FC,refertothevaluesshownfortheTPD32-EVstandardmodel.
