CAUTION
DELTA SOURCES (TN-S) - The Powerware 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.
8. The UPS cabinet is shipped with a debris shield covering the ventilation grill on top of the
unit. Do not remove the d ebris shield until installation is complete. However, remove the
shield before operating the UPS. Once the debris shield i s removed, do not place objects
on the ventilation grill.
9. Refer to Section I of this manual for installation instructions.
