6. The bypass feed into this equipment uses three or four wires. The rectifier feed into this
equipment uses three wires. Th e 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 j umper must be installed. DO NOT install both a source neutral
and a bonding jumper. See Table E through Table G for neutral bonding jumper wire sizes.
Bonding jumper must be copper wire.
CAUTION
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 tranformer 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 b e installed in the UPS.
