2.10. CHANGING THE FUSES
If there is a fuse failure, contact Evertz customer service regarding the power
supply immediately. The power supplies are short circuit protected and should
not blow the fuse under a short circuit condition.
The fuse holders are located on the front of the power tray. To change the fuse for one of the supplies,
you should first disconnect the power cord for the power supply. Insert a flat blade screwdriver in the fuse
holder and turn clockwise. Pull out the fuse from the fuse holder using a small screwdriver. Remove the
blown fuse and replace with a fuse of the correct value. The correct fuse rating is marked on the front
panel. Carefully reinsert the fuse into the fuse holder. Tighten by turning the fuse holder counter
clockwise.
The correct fuse rating is shown below.
Fuse Rating:
4 amps, 250 Volt time delay, 5 x 20 mm
Check that the line fuse is rated for the correct value. Never replace with a fuse
of greater value.
