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).
Note Use fine-stranded copper conductors rated for 90°C (194°F) for North American installations.
Note The power supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts are
centered 0.625 inches (15.88 mm) apart and are 1/4-20 threaded. We recommend that you use an
appropriately sized industry standard 2-hole, standard barrel compression lug. The power supply ground
studs, located below the terminal block, are also threaded 1/4-20 and require two 1/4-inch split-ring
washers and two 1/4-20 hex nuts.
