APPENDIX A
Changing a Fuse
This appendix shows you how to remove and install fuses for the Switch.
1 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
1 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.
