4.4.1. Changing the Fuses
The fuse holder is located inside the power entry module. To change the fuses, disconnect the line
cord from the power entry module and pull out the fuse holder from the power entry module using a
small screwdriver. The fuse holder contains two fuses, one for the line and one for the neutral side of
the mains connection. Pull out the blown fuse and place a fuse of the correct value in its place. Use
time delay 5 x 20 mm fuses rated for 250 Volts with a current rating of 1 amp. Carefully reinsert the
fuse holder into the power entry module.
Check that the line fuse is rated for the correct value marked on the rear
panel. Never replace with a fuse of greater value.
