Note:
*: If you use computer to control the inverter, you can control 32 piece paralleled inverters, but you can't
use one operation panel of the inverter to control 32 piece paralleled inverters.
﹡ If the user connects adjustable potentiometer between +10V and GND, the resistance of the
potentiometer shall be no less than 5kΩ,
