Connect the input power and motor cables properly; otherwise, the inverter unit
maybedamaged.
1.4.2 Commissioning and running
Cutoffallpowersuppliesconnectedtotheinverterunitbeforeterminalwiring,and
wait for at least the time designated on the inverter unit after disconnecting the

2.4 Derated application
2.4.1 Derating due to temperature
The standard ambient temperature of inverter unit is in the range of +40℃ ~ +50℃, and the rated output
current of inverter unit must be derated by 1% for every 1℃ increase when the temperature exceeds 50℃.
The current reference value multiplied by the derating coefficient (ke) is the output current at the
temperature higher than 50℃. Figure2-3Deratingduetotemperature

2.6 Hardware principles
2.6.1 Basic principles
TheinverterunitconvertsDCvoltageintoACfrequency-variablevoltageandsupportsdrivingasynchronous
and synchronous motors. The inverter unit models are classified into the 380V voltage class and 690V
voltageclass.
The inverter unit consists offuse, bus capacitor, IGBT, output reactor, and other components. Figure 2-7
