Dual AC and Dual AC with Convenience Outlets AC Input Voltage
Requirement ThevoltagesofthetwoACpowersourcesmustbethesame
withinafewvolts.Toensurethatthisrequirementisbeingmet,measure
thevoltagesbetweenthepinsofthetwoinputcables(IEC60320‐C19).
Note: AslongasthevoltageforeachdualAC2powerinputiswithin
therangeof200‐240VAC,theydonotneedtobethesame.
Thetwotoppinsarevoltageinputs.Thebottompinisground.Asshown
inFigure325,thetopinputvoltagepinsarelabeledAandB,fromleftto
right,andthebottompinsarelabeledC.Confirmthefollowing
measurements:
 ThevoltagefromAtoAorBtoBshouldbelessthan4V. 
 ThevoltagefromAtoBorBtoAshouldbebetween200and240V.
 ThevoltagebetweenanyAorBpintoeitherCpinshouldbeabout
120V.
Eachlibraryframeisratedat200–240VACat13amps(2600watts
maximum).Thispowerratingisbasedonamainframewith24LTOdrives
and6RIMs,whichistheconfigurationformaximumpowerconsumption
byasingleframe.Theframesarenotratedat120VACduetothehigh
currentrequiredto
