3.3.2.2 AC Operation – Replacing Fuses
For AC operation the CDM ‐ 750 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 ‐ 9 ).

Pull the holder straight out, and then swing the holder away from the module.
•
Then, remove and replace the T4A (4 Amp) fuses as needed.
FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES WITH THE
CORRECT TYPE AND RATING.
