APPENDIX A

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.
