The bypass feed into this equipment uses three or four wires. The rectifier feed into thisequipment uses three wires. The phases must be symmetrical about ground (from a Wyesource) for proper equipment operation.7. If the load requires a neutral, a bypass source neutral must be provided. If the load doesnot require a neutral and there is no neutral conductor connected at the bypass input, aneutral to ground bonding jumper must be installed. DO NOT install both a source neutraland a bonding jumper. See Table E through Table H for neutral bonding jumper wire sizes.Bonding jumper must be copper wire.C A U T I O NHIGH IMPEDANCE GROUND SOURCES - If the source of supply is a high impedance ground (IT)type, the input neutral conductor must be connected from the source of supply. If there is nooutput neutral connected to the UPS, the neutral-forming transformer kit (PN 103005400) maybe used instead of pulling a neutral from the source. If the load requires a neutral then aninput neutral conductor must be pulled into the UPS. In no circumstances shall a neutral toground bonding jumper be installed in the UPS.
