*1. Capacity is calculated at 440 V for the 480 V class.
*2. Indicates rated output current setting when the PWM carrier frequency (parameter F300) is 4 kHz.
*3. Lower limit of voltage for 480 V class is 342 V when the inverter is used continuously (load of 100%).
*4. Required power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and wires).
*5. The top cover included in the package must be installed with inverter, it is Type1 without the top cover.
*6. These acoustic noise values are not guaranteed because they are just reference values.
