What happened?
The Main Control Unit on the MMU control board has detected a power-related issue.
How to fix it?
Do not touch, move, connect, or disconnect any cables or electronic components while the printer is on. This can result in irreversible damage!
Access the MMU control board, and inspect it visually to spot any incorrect assembly or damage on its surface, on the cables, and attempt reseating the cables to ensure their connection. In particular, make sure that the PD-board add-on is attached to the control board.
