To replace the fuse:

Power Supply and
detach the power cord from the rear of
PWR-3030
Power Supply.
2. Open the fuse compartment located inside the Power Entry Module by
inserting a small flathead screwdriver into the slot below the ON/OFF
switch. Turn the screwdriver to gently pry open the fuse compartment.
Note:
the fuse compartment will not open with the power cord in place.
3. Pull the fuse holder out of the compartment and inspect the fuse. If the fuse
is burned or there is a break in the fuse element, replace the fuse with an
identical type of fuse (4A/250V~) as provided in the fuse holder (see figure
