DELTA SOURCES (TN‐S) - The Eaton 9390 UPS system can be operated only from a delta supply source that is fully floating
and if the neutral‐forming transformer kit (PN 103005400) is installed in the UPS. The UPS cannot be operated from a
mid‐point or end‐point grounded delta supply source. With this type of supply source, there is no capability to provide an
output neutral. In no circumstances shall a neutral to ground bonding jumper be installed in the UPS.
