Replacing Fuses
Periodically, you may need to replace a fuse on MAGPIX. Use fuses with the following
specifications:
• F2A, 250 V
The fuse cartridge will accept either 5 mm x 20 mm or 0.25” x 1.25” fuses. Fuses are
available from Luminex Corporation. Replacing a fuse requires access to the back of
MAGPIX.
DANGER: To avoid serious injury or death by electric shock, turn off
MAGPIX and unplug it from the wall before replacing a fuse.
To replace a fuse:
1. Unplug the power cable from the instrument.
2. Use a small, flat blade screwdriver to open the power module door on the lower right
corner of the back of the instrument. The door opens downward. Inside is a red
cartridge.
3. Use the screwdriver to remove the cartridge.

4. Check both of the fuses in the cartridge for damage. A fuse can display physical
evidence of damage, for example, broken wire or blackened glass; if it displays no
physical evidence, test it for continuity with a voltmeter.
5. Replace any damaged fuse with the correct type of fuse.
6. Replace the cartridge.
7. Shut the module door.
8. Plug in the power cord and turn on MAGPIX.
