*1 Be sure to mount the DC reactor. It is not required for DC power input terminal. A circuit between the terminals [PA/+] and [PO] is not short circuited
(at the time of shipping).
*2 To input DC power, connect the inverter between the terminals [PA/+] and [PC/-]. It is not used in conjunction with the DC reactor option DCL1.
*3 When the inverter is used with a DC power supply, a circuit to suppress an inrush current is required. Please contact your Toshiba distributor for
information.
*4 When the inverter is used with a DC power supply, three-phase power input for cooling fan driving is required separately.
*5 When a braking resistor (optional) is mounted, a braking unit (optional) is also required.
*6 For the switch function, refer to [2. 3. 5].
*7 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].
*8 The reset signal is activated by ON→OFF trigger input.
*9 Connect to power to comply with OVC2 (Over Voltage Category 2). Isolation transformer is necessary when connecting to power supply (OVC3).
