Fuse Replacement
The main fuse is located behind the power cord input assembly. Perform
the following procedure to replace the main fuse.
CAUTION: For continued protection against the possibility of fire,
replace the blown fuse only with a fuse of the same voltage,
current, and type.
1. Turn off the 2500 and remove the power cord.
2. Use the edge of a flat-blade screwdriver to pry open the door
covering the fuse holder, as shown in Figure 7-1.
Note: Only the fuse in the fuse holder is connected to the circuitry. The fuse on
the left is a spare.
3. Pull the fuse holder out of its slot, as shown in Figure 7-2.
4. Determine if the fuse is intact. If it is blown, install a new fuse of the
same size and rating (5A SlowBlow for 100/120V systems and 3A
SlowBlow for 220/240V systems).
