Chapter 5 Removal and Replacement Procedures
Removing and Replacing the Power Supply
Figure 5-76 4000 W DC-Input Power Supply Front Panel
Note Figure 5-76 shows PWR-4000-DC with an outer terminal block cover; an earlier version of this power
supply does not have an outer terminal block cover. To order a retrofit kit use part number
CVR-4000DC-TERM=.
Warning Power supply captive installation screws must be tight to ensure protective grounding continuity.
Step 5 Remove the two A4 screws securing the outer terminal block cover, and remove the cover from the power
supply (
Figure 5-76).
Step 6 Remove the two screws securing the left inner terminal block cover and one screw securing the right
inner terminal block cover.
Note You must remove three terminal block covers for the 4000 W DC-input power supply: one outer
terminal block cover and two inner terminal block covers.
Step 7 Attach the appropriate lugs to the DC-input wires and ground wire. The wires should be sized according
to local and national installation requirements. Use only copper wire.
