DELTA SOURCES (TN-S) - The 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.
