Warning Power supply captive installation screws must be tight to ensure protective grounding continuity.
Step 5 Remove the four screws securing the terminal block cover, and slide the cover off of the terminal block
(

Step 6 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. The maximum width of a lug is
0.600 inch (15.2 mm).
