[Standard connection diagram – source logic]
This diagram shows an example of a standard connection.
Power supply
Three-phase 380 - 480 V-50/60 Hz

*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 supply
unit (CPS002Z) is required. In this case, it is used in conjunction with the inverter internal power supply.
Set <F647: Control power option failure detection> to back up the control power supply.
For details, refer to [6. 30. 20] of E6582062.
*6 The reset signal is activated by ON OFF trigger input.
*7 Connect to power to comply with OVC2 (Over Voltage Category 2). Isolation transformer is necessary when connecting to power supply (OVC3).
