While the inverter is in Programming mode, the LEDs of Hz and kW light. Hz A kW
Lights when the data to display exceeds 9999. When this LED lights, the "displayed value x 10" is the actual
value.
Example: If the LED monitor displays
1234
and the x10 LED lights, it means that the actual value is "1,234
10 = 12,340."
The USB port with a Mini-B connector enables the inverter to connect with a PC with an USB cable.
