• NEVER touch the areas outlined in red in the photos below. This is to prevent electric shock caused by residual charge.
  • A residual charge of about 100V-400V remains in the AC circuits on the PSU board for several months, even when the board has been removed from the machine after turning off the machine power and unplugging the power cord.
  • The procedure to discharge residual charge from the machine by unplugging the power cord from the AC wall outlet and pressing the main power switch works only for the DC circuits on this board.  Residual charge remains in the AC circuits.
