Replacing fuses 4-27
The detector requires two 100 to 240-VAC, 50 to 60-Hz, F 3.15-A, 250-V fast
blo, 5 × 20 mm (IEC) fuses.
Suspect a fuse is open or otherwise defective when
• the detector fails to power-on.
• the fans do not operate.
To replace the fuses:
Requirement: Replace both fuses, even when only one is open or otherwise
defective.
1. Power-off the detector and disconnect the power cord from the power
entry module.
2. Pinch the sides of the spring-loaded fuse holder, which is above the
power entry module on the rear panel of the detector. With minimum
pressure, withdraw the spring-loaded fuse holder.
Warning: To avoid electric shock, power-off and unplug the
instrument before checking the fuses.
Warning: For continued protection against fire hazard, replace fuses
only with those of the same type and rating.
