Adjustments
Wiring is different for 415V ovens; refer to corresponding wiring diagram.
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 45.)
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 45.)
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 44 for the location of the wiring diagram on the oven, or page 45 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: 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.
