a. The galvanometer signal: 220V AC connected to input(L,N), output(V+,V-) connected to VIN of driver, laser control wire connected to control board which mentioned in the above picture.

b. Control board and galvanometer: 220V AC connected to input (L, N), output (V+, GND, V-) connected to power input as in the below picture.

c. Connect 220V AC as below: Put two 220V AC power supply’s L,N together, then plug into power.
