To connect 2-phase lights to a 3-phase circuit, first create a circuit that has 3 poles. Use the DM Electrical->Circuiting and Homeruns->Circuiting command. Select the circuit and press the “Change # Of Poles” button on the right side of the dialog.
Use the “Circuit to Phase” command to circuit the light fixtures to specific phases of the circuit. You will be prompted for the phase to use for the first light fixture you circuit.
After you circuit one fixture, you can press ENTER once, then type “S” to change the phase that you are connecting devices to.
