J Setting the Power Supply Voltage Jumper (400 V Class Inverters of 18.5 kW or
Higher)
Set the power supply voltage jumper after setting the input voltage constant (E1-01) for 400 V class Invert-
ers of 18.5 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 when shipped. If the power supply voltage is not 440 V, use the follow-
ing procedure to change the setting.
1. Turn OFF the power supply switch and wait for at least one minute (three minutes for models larger
than 30 kW) before removing the front panel and setting the jumper.
2. Remove the front cover.
3. Insert the jumper at the position for the voltage supplied to the Inverter (see Figure 5.1).
