Rated specifications per inverter
The following table shows the rated specifications per inverter. (For the rated specifications for operating two or three inverters
in parallel, refer to page 100.)

DC power supply voltage
Control power supply auxiliary input
Permissible control power supply auxiliary input fluctuation
Protective structure (IEC 60529)
Approx. mass (kg)

The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.

The rated output capacity indicated assumes that the output voltage is 440 V.

The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty,
allow time for the inverter and motor to return to or below the temperatures under 100% load.

The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range.
However, the maximum point of the voltage waveform at the inverter output side is the power supply voltage multiplied by about

FR-DU08: IP40 (except for the PU connector section)

For the power voltage exceeding 480 V, set Pr.977 Input voltage mode selection. (For details, refer to the FR-A800 Instruction Manual
(Detailed).)
