8.0 BACK PANEL CONNECTIONS
8.1 General. Figure2showstheback panelconnectionsforbothversionsofthe
DPAC1U, theTand COptions.It should benotedthat these ACDistribution
Panelsare speciallydesigned foruse withUNIPOWER Telecom’sINV2500
andINV2500-HSsinewaveinverters.Theymayalso,however,be usedwith
other115VACinvertersor ACpowersources.
8.2 Inverter Inputs.Bothversions ofthe DPAC1Uhaveprovisions forthe
inputsofup to fourinverters, two oneachA orB side.Eachinverter input
canhave up to25 amperesAC.Ifashelf withtwoinvertersinparallel isused,
twocables mustbe connectedfromthe inverteroutput totheDPAC1U, one
toeach of the Aside or Bside inputs(1 and 2).In this casetheinverterinput
canbeup to 50amperes AC.SeeFigure4(b).
Itshould benotedthatall invertersconnected totheDPAC1U musthave their

8.3 Terminal Strip Connections. Forthe“T” outputoption there aretwo 10-
terminalbarrierstrips oneachA andBside ofthepanel. Asshownin Figure
2,each A andBside hasconnectionsfor twoinverterinputs (upto25A
each)and fouroutputloads(up to50A totaloutput).For eachinverterinput
andeachoutputloadthereareline,neutral andground connectionterminals.
Eachterminalstrip outputis ratedup to30 amperes.
8.4 NEMA 5-15R and Positronics Connections. Forthe “C”output optionthe
inputconnections areto Positronics connectors,one foreachofthefour
inverterinputs. Theconnector isno. PLA03MI10000withMC112N contacts;
themating connectorisPLA03F0050withFC112N2contacts. SeeFigure 5
