SERVICING INSTRUCTIONS
CAUTION: These servicing instructions are for use by qualified service
personnel only. To reduce the risk of electric shock, do not perform any
servicing instructions in this section of the manual unless you are qualified to
do so.
2.6.1. Changing the Fuses
CAUTION: For continued protection against the risk of fire, replace only with the
same type and rating of fuse.
ATTENTION: Pour éviter les risques d’incendie, remplacer le fusible avec un
fusible de même calibre.
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 the fuse holder out 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.
For 100-120 VAC operation, use ceramic time delay 5 x 20 mm fuses rated for 250 Volts with a 10 amps
current rating. For 220-240 VAC operation use ceramic time delay 5 x 20 mm fuses rated for 250 Volts
with a 6.3 amps current rating.
For your convenience there are spare fuses located in the vinyl pouch in the front of this manual.
Carefully reinsert the fuse holder into the power entry module.
