then disconnect the power cord from the mains power.
With the ITC5xx turned over, remove the two screws that secure the cover to the
chassis.
Remove the unit by sliding it out of the cover. With the unit set upright, you will find
the label depicting names, values and positions of internal fuses at the outer wall of
the transformer section.
Replace the defective fuse, and reattach the cover.
