Step3. Mount the PSU (Power supply unit) on the right side panel with 3 M3 x 10
screws.
Step5. Now we can connect the wires to the PSU.
1) Mind the color of the wires. The wrong connection of the wire will cause serious
damage to the PSU and even to the control board of the printer.
As you can see, there are 7 wires and 9 screws in total.
Note the correspondence between the color of wires and the connector.
