Preventive Maintenance and Fault-finding

5.9.4 AC Equipment Fuse Replacement

Warning!

Always disconnect the equipment from the AC supply before replacing the rear

panel fuse. Failure to do so may expose personnel to hazardous voltages.

Caution!

When replacing the AC supply inlet fuse always ensure that a fuse of the correct

type and rating is fitted. Failure to do so may result in inadequate protection to the

equipment.

To replace the AC supply fuse, perform the following:

1. Switch OFF power, then disconnect the power cable from the AC supply inlet.

2. Ease out the fuse carrier with a small, flat-blade screwdriver (or similar tool) in

the notch at the top of the carrier (see Figure 5.1).

3. Check that the replacement fuse is of the correct type and rating, then insert into

the carrier.

4. Insert the fuse carrier back into the AC supply inlet.

Note: If the replacement fuse also blows, do not continue. Disconnect the

equipment and contact Ericsson Customer Services for advice.
