E65821622-11 2. Installation and wiring Standard connection diagramThis diagram shows a standard wiring of the power circuit and control circuit.[Standard connection diagram – source logic]This diagram shows an example of a standard connection.*1 External braking resistor (option).*2 To input DC power, connect the inverter between the terminals [PA/+] and [PC/-].*3 When using models of VFAS3-4220PCE to VFAS3-4750PCE with a DC power supply, a circuit to suppress an inrush current is required. For detail,refer to application manual "DC power supply connect to inverter" (E6582156).*4 For the switch function, refer to [2. 3. 5] of E6582062.*5 To supply control power from an external power supply for backing up the control power supplied from the inverter, an optional control power supplyunit (CPS002Z) is required. In this case, it is used in conjunction with the inverter internal power supply.Set to back up the control power supply. For details, refer to [6. 30. 20] of E6582062.*6 The reset signal is activated by ONOFF trigger input.*7 Connect to power to comply with OVC2 (Over Voltage Category 2). Isolation transformer is necessary when connecting to power supply (OVC3).+SUCCFLAFLBFLCR1A/R2AR1C/R2CFM AM CC RX II RR PPSTOBSTOAPLCPLCSINKSOURCESW1*4* 5*1*2*3*5FPPulse counterCCS5S4S3S2S1RESRF Fwd runRev runReset 1Preset speed switching 1Preset speed switching 2Preset speed switching 3Preset speed switching 4Preset speed switching 5Common*6Digital inputP24Power supplyThree-phase 380 - 480 V-50/60 HzControlcircuitDC/DCPowercircuitEMCfilterDC reactorVoltage signal: -10 to +10 VAmmeter or voltmeterCurrent signal: 4(0) to 20 mAR/L1 U/T1V/T2MMotorW/T3PA/++DC -DCPB PC/-S/L2T/L3MCCB or ELCBDefaultsetting(Or, input voltage signal of 0 - 10 V between the terminals [RR] and [CC])External potentiometerFrequencymeter Ammeter*7
