Chapter 4 Removal and Replacement Procedures
Removing and Installing the DC-Input Power Supplies
Caution Use both hands to install and remove the power supplies. Each DC-input power supply weighs 32 pounds
(14.5 kg).
Step 4 Grasp the power supply handle with one hand, and place your other hand underneath the power supply.
Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the
bay. (See Figure 4-29.)

Step 5 Tighten the power supply captive installation screws. (See Figure 4-27.)
Step 6 Remove the two screws that secure the outer terminal block cover, and remove the cover from the power
supply. (See Figure 4-27.)
Step 7 Remove the two screws that secure the left inner terminal block cover, remove the cover, and set it aside.
Remove one screw that secures 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.
Note You must install the plastic insulators that are shipped with the power supply.
Step 8 Place both plastic insulators over the terminal areas, aligning the circular holes in insulating cover with
terminal posts. The protective end flap on the plastic cover is opposite the wire entry area. The protective
end flap must fold down and cover the open side of the terminal (opposite side from wire entry).
Note Be sure to place a plastic insulator over the smaller terminal block, even if you are not attaching
DC-input wires to it; this action ensures that the plastic insulator is available for future use.
