Wiring is different for 415V ovens; refer to corresponding wiring diagram (see page 30).
7. Locate the wires running from the contactor to the elements. If converting from three-phase to single-
phase power, remove the wire L2 (as shown in the above drawing) and go on to the next step. If
converting from single-phase to three-phase power, use the longer of the two extra wires found in the
previous step to make the additional connection (L2) shown in the above drawing. (Again, if you are
changing the phase-wiring of a 415V oven, refer to the corresponding wiring diagram for conversion.
See page 30.)
8. Rewire the connections to the elements (located on the back of the oven) according to the diagram at
the top of this page. If converting from three-phase to single-phase, use the wire that you saved in Step
2 to make one of the connections. (Once more, if you are changing the phase-wiring of a 415V oven,
refer to the corresponding wiring diagram for conversion. See page 30.)
9. Carefully compare the new wiring connections at the elements, contactor, and supply-power
terminal block to the wiring diagram for the oven. (See page 30 for the location of the wiring
diagram on the oven, or page 30 for wiring diagrams printed in this manual). Verify that all
connections are tight.
10. Reattach the element-cover box, right-side panel, and lower-front panel.
11. Connect the oven to the power supply according to the procedure on page 15. Note that the supply-
power connections depend on whether the supply power is three-phase or single phase, and so
will be different than they were prior to the conversion.
12. Double-check supply-wire sizing for new amperage load (see page 4).
