Attach the appropriate lugs to the DC-input wires and ground wire. The wires should be sized according
Step 6
to local and national installation requirements. Use only copper wire. The maximum width of a lug is
0.600 inch (15.2 mm).
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
Note
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.
