Due to internal wiring differences of the operation of a 4 Wire Wye load, an additional wire harness must be
ordered. If 4 Wire Wye is specied at the time of purchase the controller will ship from the factory wired for 4
Wire Wye operation.
The Fusion controllers normally display line and load voltages from Line to Line. When the controller is in 4
Wire Wye operation the line voltages read Line to Line while the load voltages read Line to Neutral.
There are instructions in Appendix B showing how to change from 4 Wire Wye to a standard conguration
(Delta or 3 Wire Wye). Both wire harnesses are necessary to perform this task.
For ordering details see Appendix B in the Operator Manual. The model number conguration data is 0002.
