So if you are using single-phasemodels, use the R/L1 and S/L2/N terminals to connect power cables.■ Power circuitTerminal symbol Terminal functionGrounding terminal for connecting inverter. There are 3 terminals in cooling fin ormounting part of EMC plate.R/L1,S/L2,T/L3240V class : Three-phase 200 to 240V-50/60Hz: Single-phase 200 to 240V-50/60Hz500V class : Three-phase 380 to 500V-50/60Hz* Single-phase inputs are R/L1 and S/L2/N terminals.U/T1,V/T2,W/T3 Connect to three-phase motor.PA/+, PB Connect to braking resistors.Change parameters , , , if necessary.PA/+ This is a positive potential terminal in the internal DC main circuit.DC common power can be input with PC/- terminal.PC/- This is a negative potential terminal in the internal DC main circuit.DC common power can be input with PA/+ terminal.PO, PA/+ Terminals for connecting a DC reactor (DCL: optional external device). Shorted by ashort bar when shipped from the factory. Before installing DCL, remove the short bar.The arrangements of power circuit terminals are different from each range.Refer to section 1.3.3.1) for details.
