The power supply voltage jumper must be set for 400 V Class Inverters of 75 kW or higher. Insert the jumper
into the voltage connector nearest to the actual power supply voltage.
The jumper is factory-set to 440 V. If the power supply voltage is not 440 V, use the following procedure to
change the setting.
1. Turn OFF the power supply and wait for at least 5 minutes.
2. Confirm that the CHARGE indicator has gone out.
3. Remove the terminal cover.
4. Insert the jumper at the position for the voltage supplied to the Inverter (see Fig 4.2).
5. Return the terminal cover to its original position.
