APPENDIX D
Removing and Installing a Fuse
This appendix shows you how to remove and install fuses for the IES-1248-51A.
If you need to install a new fuse, follow the procedure below.
Note: If you use a fuse other than the included fuses, make sure it matches the fuse
specifications in Appendix B on page 445.
Removing a Fuse
Note: Disconnect all power from the IES-1248 before you begin this procedure.
1 Remove the power cord from the unit.
2 The fuse housing is located between the power switch and the power port. 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.
Installing a Fuse
1 The IES-1248 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 Firmly, but gently, push the fuse housing back into the IES-1248 until you hear a click.
4 Plug the power cord back into the unit.
