Removal and Replacement Procedures
Removing and Installing the DC-Input Power Supplies
Step 3
Remove the two screws securing the outer terminal block cover, and remove the cover from the power
supply. (See
Figure 4-24
.)
Step 4
Remove the two screws securing the left inner terminal block cover, remove the cover, and set it aside.
Remove one screw securing the right inner terminal block cover, remove the cover, and set it aside.
Note
You must remove three terminal block covers for the 4000 W DC-input power supply. The
left-side inner terminal block cover has two securing screws, and the right-side inner terminal
block cover has one securing screw.
Step 5
Remove the plastic insulator from over the terminal area. (See
Figure 4-25
.)
Step 6
Disconnect the DC-input wires from the terminal block in this order:
1.
Positive (+)
2.
Negative (-)
3.
Ground
You must remove all DC-input wiring from both terminal blocks.
Note
You must remove DC-input wires from two terminal blocks for the 4000 W DC-input power
supply (if both terminal blocks are used).
