The bypass feed into this equipment uses three or four wires. The rectifier feed into this
equipment uses three wires. The phases must be symmetrical about ground (from a Wye
source) for proper equipment operation.
7.
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 to ground bonding jumper must be installed. DO NOT install both a source neutral
and a bonding jumper. See Table E through Table J for neutral bonding jumper wire sizes.
Bonding jumper must be copper wire. See Following Cautions.

HIGH 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 no output neutral connected to the UPS, the
neutral‐forming transformer kit (PN 103005400) may be used instead of pulling a neutral from the source. If the load requires
a neutral then an input neutral conductor must be pulled into the UPS. In no circumstances shall a neutral to ground bonding
jumper be installed in the UPS.
