Revision 2 User's and Installation Guide
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.
