9.3.2 Protection Function

9.3.2.1 Protective Functions

The power supply PCB is equipped with an over-current/over-voltage protection mechanism to prevent damage
to the power circuit in the event of an over-current or over-voltage, as caused by a short circuit or the like on the
load side.
If the over-current/over-voltage protective mechanism has gone ON, disconnect the power cord, and correct the
fault; then, connect the power cord once gain to reset the machine. If short circuiting and resetting are repeated,
the internal fuse (F1, F2) can melt.
