Warning
Power supply captive installation screws must be tight to ensure protective grounding continuity.
Note
With the PWR-6000-DC power supply, you have the option of installing an Input Power Module (IPM)
(previously removed) with the DC-input wires and the ground wires still connected. You can then install
your power supply and insert the fully-wired IPM. If you are going to install an IPM with DC-input wires
and ground wires still connected, skip steps 4 through 12 and go directly to step 13.
Step 4
Remove the two A4 screws securing the outer terminal block cover, and remove the cover from the power
supply (
Figure 5-82
).
Step 5
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.
