Note
With the PWR-6000-DC power supply, you have the option of removing the Input Power Module (IPM)
without disconnecting the DC-input wires and the ground wires. You can then replace your power supply
and insert the fully-wired IPM. To use this option, do not perform steps 3 through 6 and go to step 7.
Step 3
Remove the two A4 screws securing the terminal block cover, and remove the cover from the power
supply (
Figure 5-35
).
Step 4
Cut any cable tie-wraps being careful not to cut the DC-input wires.
