*1
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 converter unit and the inverter to return to or below the temperatures under 100 % load.
*2
The converter unit output voltage varies according to the input power supply voltage and the load. The maximum point of the voltage
waveform at the converter unit output side is approximately the power supply voltage multiplied by √2.
*3
The power supply capacity is the value when at the rated output current. It varies by the impedance at the power supply side (including
those of the input reactor and cables).
*4
The permissible voltage imbalance ratio is 3 % or less.
(Imbalance ratio = (highest voltage between lines – average voltage between three lines) / average voltage between three lines × 100)
