● Regarding to characteristic for aul=1 setting, refer to section 5.6.3).
Note 1) In case of aul=2 setting, be sure to install the input AC reactor (ACL) between power supply and inverter.
Note 2) In case of aul=2 setting in three phase 500V-4.0kW model, be sure to press the grounding capacitor
switch and connect the grounding capacitors to the ground.
