Changing a Fuse
This appendix shows you how to remove and install fuses for the Switch.
If you use a fuse other than an included fuse, make sure it
matches the fuse specifications in the appendix on product
specifications.
Removing a Fuse
Disconnect all power from the Switch before you begin this
procedure.
1
Remove the power cord from the Switch.
2
See the product specifications for the location of the fuse. Use a small flat-head
screwdriver to carefully pry out the fuse housing.
3
A burnt-out fuse is blackened, darkened or cloudy inside its glass casing. A
working fuse has a completely clear glass casing. Pull gently, but firmly, to
remove the burnt out fuse from the fuse housing. Dispose of the burnt-out fuse
properly.
Installing a Fuse
1
The Switch is shipped from the factory with one spare fuse included in a box-like
section of the fuse housing. Push the middle part of the box-like section to access
the spare fuse. Put another spare fuse in its place in order to always have one on
hand.
2
Push the replacement fuse into the fuse housing until you hear a click.
3
Push the fuse housing back into the Switch until you hear a click.
4
Plug the power cord back into the unit.
