● Regarding to characteristic for aul=1 setting, refer to section 5.6.3).
Note) In case of aul=2 setting, be sure to install the input AC reactor (ACL) between power supply and inverter,
to remove the protective label on the top of the inverter, and to connect the grounding capacitors by
pressing the grounding capacitor switch.
Then, to use the inverter at 40°C or less of the ambient temperature with setting f300 to 4.0 kHz or less.
