Power Fuse Replacement 3
Preliminary Steps Before replacing the power fuses, shut off the power; lockout/tagout the
unit; and wait five minutes for the voltage to discharge. Open the bay door
to the power fuses.
Replacing the Power Fuses 1. Using a meter, test the voltage across the AC line, across the DC bus, and
across each of the power fuses.
2. Remove the two bolts from the fuse and pull the fuse out.
3. Verify that the new fuse has the same rating as the old fuse (or check
your user manual for the appropriate fuse rating).
4. Secure the new fuse using the torques below:
5. Repeat for each fuse to be replaced.
