Figure 3-10. Apply AC Power to the CDM-625A
To apply AC power to the CDM-625A (Figure 3-10), do these steps:
• First, plug the provided AC power cord female end into the unit.
• Then, plug the AC power cord male end into the user-supplied power source.

3.3.2.3 AC Operation – Replace the Fuses
For AC operation the CDM-625A 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 3-11).
