3.11.1. Cooling Fan Supply Voltage Selection (400V class)

The inverter input voltage range of the VDI100 400V class models ranges from 380 to 480Vac. In these models
the cooling fan is directly powered from the power supply. Inverter models VDI100-6900 ... 71600 requires the
user to select the correct jumper position based on the inverter input voltage ("440V" is the default position for
these models). Please select the correct position according to the input voltage. If the voltage setting is too
low, the cooling fan will not provide adequate cooling for the inverter resulting in an over-heat error. If the input
voltage is greater than 460Vac, select the "460V" position.
