3.11.1 Cooling Fan Supply Voltage Selection (400V class)
The inverter input voltage range of the A510s 400V class models ranges from 380 to 480Vac. In these
models the cooling fan is directly powered from the power supply. Inverter models A510s-4215(F8)/
4270/ 4300/ 4375/ 4425 requires the user to select the correct jumper position based on the inverter
input voltage ("400V" 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.
(1) 400V: 270HP~425HP
