• The bypass feed into this equipment uses four wires. The rectifier feed into this equipment uses
three or four wires. The phases must be symmetrical about ground (from a Wye source) for
proper equipment operation.
• If the load requires a neutral, a bypass source neutral must be provided. If the load does not
require a neutral and there is no neutral conductor connected at the bypass input, a neutral must
be installed to source star point.
• A readily accessible disconnect device must be incorporated in all fixed input wiring.
