*1: Models 230V class 0.75 ~ 18.5kW and 400V class 0.75 ~ 30kW or lower ratings have a built-in braking transistor. To use this braking transistor a braking resistor can be

connected between B1 and B2.

*2: Use SW3 to select between Sink (NPN, with 24VG common) or Source (PNP, with +24V common) for multi-function digital input terminals S1~S8.

*3: Use SW2 to switch between voltage (0~10V/-10~10V) and current (4~20mA) input for Multi-function analog input 2 (AI2).

*4: Run Permissive input F1 and F2 is a normally closed input. This input should be closed to enable the inverter output. To activate this input remove the jumper wire between

F1 and F2.

*5: Models 230V Class 2.2kW and 400V Class 3.7kW and higher ratings include terminals -10V, S(+), S(-),R2A-R2C and PO-GND.

*6. 230V Class 1.5kW and 400V Class 2.2kW and lower ratings include terminal DO2.

*7: When using the open collector for pulse input, it doesn’t need resistance because of built-in pull-up resistance.

*8: AO2 default setting is 0~+10V.

*9: 400V class 75kW~160kW have built-in DC reactors.

*10: It need turn on the switch for the terminal resistor RS485 in the last inverter when many inverters in parallel connection. Please refer to Appendix A
