*2:Multi-function analog input/ output can be referred to in our instruction manual..
- Group 04 - External Terminal Analog Signal Input (Output) Function Group.
Caution
Maximum output current capacity for terminal 10V is 20mA.
Multi-function analog output AO1 and AO2 are used for an analog output meter. Do not use
these outputs for feedback control.
Control board’s 24V and ±10V are to be used for internal control only, Do not use the internal power-
supply to power external devices.
2.5 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-4150/ 4175/ 4215/
4270/ 4300/ 4375/ 4425 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.
(1) 400V： 150HP～215HP (F7)
(2) 400V：215HP(F8) (Note)～425HP
Note: The spec. please refer to Chapter 3.7, the rated current is 330/370A.
