Routine Maintenance . 73
Changing the External Fuse
Very occasionally, a fuse may fail with age and will need to be changed.
NOTE: If fuses fail repeatedly, there is an electrical fault: disconnect the power supply and
contact your PerkinElmer Service Engineer.
There is one spare fuse in the fuse drawer. If you need more, order 2 A, 250 V Time Lag
fuses (part number 04970839) from PerkinElmer. You must only replace the fuse with one of
this type and rating. Do not use makeshift fuses and do not short-circuit fuse holders.
WARNING
Before you begin this procedure, switch off the power to the
spectrometer, wait for 60 seconds, and disconnect the power cable.
This will protect you from electrical shock.
The external fuse drawer is located at the rear of the instrument between the power switch
and the power socket (Figure 38).
