Figure 1 Figure 2
Remove the mains power supply cord from the connector
on the power entry module, located on the APx517 rear
panel. The mains fuse carrier module is part of the power
entry module, below the power switch.
Insert a small screwdriver into the slot at the bottom of the
power entry module as shown in figure 1, and pry open the
hinged door to reveal the red mains fuse carrier module.
Lift the fuse carrier module with the screwdriver as shown
in Figure 2, and then pull it out of the power entry module
using your fingers. The two mains fuses are loosely
mounted within the fuse carrier module; take care not to let
them fall.

Replace the fuses if necessary, using fuses as described
above. Note that the fuses mount between the center con-
tact clip and the contact nearest the module pins, as shown
in figure 3 and 4. Carefully reinsert the fuse carrier module
into the power entry module, and press it firmly into place.
Firmly close the hinged door.
Connect the power cord from a mains power outlet to the
power cord connector on the APx517 rear panel.
