Input Wiring Procedure

1.Refer to figure 4-3. Locate the input wiring entry and input wiring inspection panels.

2.Remove the four screws securing the panels to the frame. Remove only the screws indicated in the illustration. Place the screws and panels to one side.

2.Pull the three input wires through conduit, leaving about 20” of wiring extending from the end. Install a flexible metal conduit connector to the end of the conduit. Using appro- priate tools, remove the knockout in the entry panel. Feed the wires through the entry panel, and attach the flexible metal conduit connector to the panel. Strip 1/2” of insulation from the end of each of the incoming wires.

3.Feed wire into the entry compartment through the wiring pathway hole between the input wiring entry compartment and the input wiring compartment. See figure 4-4 for the input wiring pathway.

4.Connect input wires to the input terminal block connec- tions labelled L1, L2/N and Ground as shown in figure 4-5. Make sure there are no loose strands and that the terminal connection screws are sufficiently tightened. Connections are the same for 208V or 240V incoming voltages.

Note: In North America, L2/N is a phase (hot) connection. In Europe, L2/N indicates a neutral connector.

5.Carefully fold the excess wiring into the entry compart- ment. After the electrical wiring test/checklist is completed (end of this chapter), replace the input wiring panels.
