APPENDIX A

Changing a Fuse

This appendix shows you how to remove and install fuses for the IES-612-51 (DC model

only).

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 IES-612-51 before you begin this procedure.

1 Remove the power cord from the IES-612-51.

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 IES-612-51 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 IES-612-51 until you hear a click.

4 Plug the power cord back into the unit.
