3.3.2.2 AC Operation – Replacing Fuses
FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES WITH THE
CORRECT TYPE AND RATING.
The CDD‐880 uses two 20mm Slow‐blow fuses – one each for line and neutral connections. The
fuses are located in the rear panel at the power supply (Figure 3‐7).
DISCONNECT THE POWER SUPPLY BEFORE PROCEEDING!
The fuses are contained within a fuse holder that is press‐fit into the body of the IEC
power module.
Figure 3-7. Replacing CDD-880 AC Fuses
To replace the fuses:
• First, unseat the fuse holder from the IEC power module.
o Use the slot to pry the holder outward from the IEC power module.
o Pull the holder straight out, and then swing the holder away from the module.
• Then, remove and replace the fuses as needed.
o Use T3.15 (3.15 Amp) fuses for standard router operation.
• Finally, re‐seat the fuse holder in the IEC power module.
