Preventive Maintenance and Fault-finding
When the failure condition has been fully investigated, and the symptoms are
known, proceed with fault-finding according to the observed symptoms. If the fault
persists, and cannot be rectified using the instructions given in this Reference
Guide, contact Customer Services. Switch off the equipment if it becomes unusable,
or to protect it from further damage.
6.4.3 User Accessible Fuse Replacement
Fuses are held in integral fuse carriers at the AC power inlets at the rear panel.
Note: Refer to Annex B, Section B.3, Power Supply for more information about the
fuse.
To replace the AC power fuse(s):
Warning!
Before replacing the rear panel fuses, disconnect the unit from the supply. Failure to
do this may expose hazardous voltages. Unplug the unit from the local supply
socket.
1. Ensure that power is turned off and the power cable is disconnected from the
AC power inlet(s).
2. Ease out the fuse carrier by placing a small, flat-bladed screwdriver in the notch
at the top of the carrier.
Caution!
When replacing the power input fuses, always ensure that a fuse of the correct type
and rating is fitted. Failure to do so results in inadequate protection.
3. Replace the fuse in the carrier.
4. Insert the fuse carrier back in the AC power inlet.
