Checking the Main Fuse
Internal Fuse
The switching power supply contains a separate fuse. Most fault conditions should be protected
by the main fuse.
If you find it necessary to replace the internal fuse, be certain to replace it with a fuse of the same
type and rating as printed on the switching power supply board.
