LED indicators
The inverter has a control board with 2 LEDs and a control unit with 1 LED. The LEDs
show the inverter’s current operational status.
LEDs on control board
The LEDs on the control board can only be seen through the transparent section of
the front cover when the control unit is not attached to the control board and inverter.
For example, in cases where the control unit is remotely installed. The control board
has one dual color LED (1) and one red warning symbol LED (2) which highlights
active fault situations where there could be a danger of electric shock.
