Cooling Fan Supply Voltage Selection (460V class)
The inverter input voltage range of the A510 460V class models ranges from 380 to 480Vac. In these models
the cooling fan is directly powered from the power supply. Inverter models A510-4125/ 4150/ 4175/ 4215/ 4250/
4300/ 4375/ 4425-C3-U requires the user to select the correct jumper position based on the inverter input
voltage ("460V" 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.

:
270HP ~ 425HP
The inverter input voltage range of the A510 600V class models ranges from 575 to 690Vac. In these models
the cooling fan is directly powered from the power supply. Inverter models A510s-6175~627 requires the user to
select the correct jumper position based on the inverter input voltage ("690V" is the default position for these
models). Please select the correct
