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 debris shield until installation is complete. However, remove the shield before operating the UPS. Once the debris shield is removed, do not place objects on the ventilation grill.

9.Refer to Section I of this manual for installation instructions.
