Wiring Diagram
The variables displayed on the LCD and the number of decimal places can be set through the configuration software.
The LCD supports the display of two variables, which include current, primary variable percentage, and primary variable. Each variable can be independently configured to display decimal points at positions: 0, 1, 2, or 3.
If the two display variables are different, the LCD will alternate between the set variables at intervals of 3 seconds.
