WARNING…
BEFORE REPLACING THE REAR PANEL FUSE, ISOLATE THE UNIT FROM THE SUPPLY.
FAILURE TO ISOLATE THE EQUIPMENT PROPERLY MAY CAUSE A SAFETY HAZARD.
NOTE…
Refer to Annex B, Technical Specification for information about the DC fuse.
To replace the DC power fuse:
1. Ensure that DC power is turned off or the power cable is disconnected
from the power inlet.
2. Unscrew the fuse carrier and remove the old fuse (see Figure 7.3).
CAUTION...
When replacing the power input fuse, always ensure that a fuse of the correct type and rating, is fitted.
Failure to do so results in inadequate protection.
3. Insert the new fuse in the carrier.
4. Insert the fuse carrier back in the DC power inlet.
