AC input terminal for Line, Neutral and Ground of the external power cable. Connect the black Line wire to the “L” slot of the AC input terminal-block.
Connect the white Neutral wire to the “N” slot of the AC input terminal-block. A blue stripe is added to the illustration of the Neutral wire for image clarity.
The green Ground wire containing a yellow stripe is connected to the ground slot of the AC input terminal-block. The Ground wire connection is performed at the factory and terminates at cabinet-ground-stud.
The cabinet-ground-stud is the ground-star location for cabinet, cabinet-door and earth-ground of the power supply.
Connect the green Ground wire from the external power cable to the cabinet-ground-stud. This is the earth ground connection of the power supply.
Reference the ground symbol in the illustration for the location of the earth ground in the power supply.
