Ac Operation - Fuse Replacement; Figure 3-12. Ac Fuse Replacement - Comtech EF Data CDM-425 Installation And Operation Manual

3.3.2.3 AC Operation – Fuse Replacement
For AC operation, the CDM-425 Advanced Satellite Modem uses two common 5mm x 20mm
Slow-blow fuses – one each for line and neutral connections. The fuses are contained within a
fuse holder that is press-fit into the body of the IEC power module (located on the rear panel,
Figure 3-12).
WARNING! DISCONNECT THE POWER SUPPLY BEFORE PROCEEDING!
To replace the fuse(s), do these steps:
1. Unseat the fuse holder from the IEC power module.
a. Use the slot to pry the holder outward from the IEC power module.
b. Pull the holder straight out, and then swing the holder away from the module.
2. Remove and replace the T4A (4 Amp) fuses as needed.
CAUTION – FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE
THE FUSES WITH THE CORRECT TYPE AND RATING.
3. Reseat the fuse holder in the IEC power module.
