Inherent Redundancy To deliver greater reliability, the Eaton9395 UPS can be configured by an authorized Eaton Customer Service Engineer for inherent redundancy if a FI-UPM is installed. When configured, the UPS automatically becomes redundant if the load is at or below the capacity of the UPMs minus the capacity of one UPM.
UPMs in distributed bypass and parallel systems must use a separate battery system. A supplemental 48 Vdc shunt trip signal for the battery disconnect device is provided by the UPS, but is not required for normal operation. 164201716 Rev 2 www.eaton.com/powerquality Eaton 9395 550/275 UPS (225–550 kVA) Installation and Operation Manual...
