IntroductionEaton 93PM UPS (20–100 kW, 480V – 100 kW Frame) Installation and Operation Manual P-164000227—Rev 6 www.eaton.com/powerquality 1-31.1.2 Control PanelThe control panel, located on the front of the UPS, contains a color liquid crystal touch screen display (LCD) anda horizontal row of LED indicators to control the operation of the UPS and to display the status of the UPSsystem. See Chapter 6, “UPS Operating Instructions,” for additional information.1.1.3 Customer Interfacel Building Alarm Monitoring – Up to five inputs in the UPS are available to connect the facility's alarmsystem contacts. Some system configurations may limit the number of inputs available. The UPS usesthese inputs to monitor the building alarms in addition to the UPS status. See Chapter 7, “Communication,”for additional information.l Alarm Contact – One alarm contact is provided for connection to equipment at the facility, such as a light,an audible alarm, or a computer terminal. The equipment connected to this contact alerts you to a UPSalarm. See Chapter 7, “Communication,” for additional information.l Minislot Communication Bays – Four communication bays are standard equipment. One to four optionalMinislot ® connectivity cards can be installed in the UPS at any time. Minislot cards are quickly installed atthe front of the UPS and are hot-pluggable. See Chapter 7, “Communication,” for additional information.1.1.4 Energy Saver System ModeThe 93PM Series UPS offers an Energy Saver System (ESS) mode that maximizes efficiency by eliminatingunnecessary power conversion when the commercial power source is within acceptable voltage and frequencylimits. In this mode, the UPS is actively monitoring the critical bus and instantly and seamlessly transitions todouble-conversion mode (inverter online) if a commercial electrical power brownout, blackout, overvoltage,undervoltage, or out-of-tolerance frequency condition occurs. See Chapter 6, “UPS Operating Instructions,” foradditional information.1.1.5 Internal RedundancyTo deliver greater reliability, the Eaton 93PM UPS can be configured for internal redundancy. When configured,the UPS automatically becomes redundant if the load is at or below the capacity of the UPMs minus thecapacity of one UPM. Under normal conditions the UPMs in the UPS share the load equally. If one or moreUPMs becomes unavailable and the load is at or below the capacity of remaining UPMs, the remaining UPMssupply the load instead of transferring to bypass.1.1.6 UL 924 Auxiliary Lighting and Power Equipment Certification93PM models are complementary listed for “UL 924 Auxiliary Lighting and Power Equipment”, which allowsalternative battery runtimes to be used.WARNINGEmergency Power Off (EPO) and Remote Emergency Power Off (REPO) functionality is disabledfor UPS systems configured for UL 924 auxiliary lighting. To remove power from the system, aLOAD OFF command (see paragraph 6.3.15 or 6.4.17) must be given using the front panel controlsand all breakers opened.1.1.7 ENERGY STARENERGY STAR® certified UPS.
