POWER WIRING INSTALLATION NOTES011509D164201604-5NOTE: Customer ground can be run in any conduit listed in Table J.4 of 15DESCRIPTION:DATE:DRAWING NO: SHEET:REVISION:INSTALLATION INFORMATIONEaton 9390 UPS (100–160 kVA) Installation and Operation Manual 164201604 Rev E www.eaton.com/powerquality A-15C A U T I O NDELTA SOURCES (TN‐S) - The Eaton 9390 UPS system can be operated only from a delta supply source that is fully floatingand if the neutral‐forming transformer kit (PN 103005400) is installed in the UPS. The UPS cannot be operated from amid‐point or end‐point grounded delta supply source. With this type of supply source, there is no capability to provide anoutput 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 theunit. Do not remove the debris shield until installation is complete. However, remove theshield before operating the UPS. Once the debris shield is removed, do not place objectson the ventilation grill.9. Refer to Section I of this manual for installation instructions.10. Terminals are UL and CSA rated at 90°C. Refer to Table H and Table I for power cableterminations, and Table J for conduit requirements. Drawing 164201604-7 shows thelocation of the power cable terminals inside the UPS cabinet.Table H.
