Interfaces and Connections¶

PSU Connection¶
The terminal block consists of three main connection points labeled as follows and to be connected depending on PSU type and power input source:
For DC Power Supply
“+” (Positive): Connect the positive voltage supply.
“-” (Negative): Connect the negative voltage supply.
“GND” (Ground): Provides a grounding point for safety and signal reference.
For AC Power Supply
“L” (Line): Connect the AC Power Line.
“N” (Neutral): Connect the to Neutral Line
“GND” (Ground): Connect to Protective Earth
