SCOPE OF WORK/SPECIFICATIONS 1. UPS System. Contractor shall supply and install two each of Eaton 93PM UPS 20- 200kw with wiring side car for top entry electrical and seismic kits for both with top air exhaust. 480/277V in, 480/277V (4 wire) System Voltage, 50kW Rated, 150kW Frame Capacity, Standard 97% Efficiency, 99% Efficiency with ESS, Firmware expandable to 150kW, Includes Power Xpert Gateway Card, Industrial Relay Card, and EMP, Includes 7x24 Startup, and manufacturers equipment warranty. For start up UPS shall be on load bank for testing/parallel prior to connected to lottery load. 2. Paralleling UPS. These units' output shall be paralleled to provide uninterrupted power to the Lottery data center in the event of a single UPS failure and during major Preventive maintenance of each unit. Output synchronization of the UPS units shall remain 100% synchronized through a complete utility power grid outage and emergency generator source connection then back to the utility power grid utilizing the Lottery's existing transfer switch operation and features. See schematic drawings. The power circuitry feeding each UPS input and each UPS output power circuitry shall be sized to accommodate up to 150 KVA of continuous connected load. 3. Batteries / Battery Cabinets. Each UPS shall have a separate battery cabinet Eaton 93PM Lithium-Ion that will have a total of approximately 30 minutes of estimated run time load of 50 KW. Battery buss voltage from each cabinet shall be 480 VDC. This cabinet shall allow for battery maintenance of each battery cabinet individually. Each battery cabinet shall have a DC rated circuit breaker for the purpose of disconnection. Each breaker shall have an auxiliary contact that will provide remote monitoring notification that battery trouble is present. 4. Maintenance Bypass*. Each paralleled UPS shall have full external maintenance bypass circuitry that will allow for complete disconnection of either UPS from its input and output power sources for the purpose of major predictive maintenance or catastrophic failure of a single UPS for replacement purposes. See schematic drawings, Attachment E. 5. Static Bypass. Each UPS Unit must have an internal static by-pass switch that will automatically, without load interruption, by-pass systems power around failed electronics within the UPS to the output loads. 6. Battery Charging. UPS units shall have advanced battery charging and management capability with a charging temperature compensation feature. The system must also have the capability of determining the health of the batteries and predict anticipated run time with advance battery failure warning to guide maintenance staff. 7. Output Connection*. The output of the UPS systems downstream (or after the paralleling function) shall feed our existing PDU distribution panel that in turn is connected to two separate PDU units located in the Lottery's data center. 8. Remote Monitoring. Each UPS shall have one network interface card (Currently using predict pulse) that will allow the Lottery to monitor the units through a remote PC on its IP based network system or monitoring company. 9. Critical System Outage. The Lottery's goal is to maintain zero down time of its critical systems and equipment throughout the UPS installation and conversion process. Any down time of UPS connected loads must be predicted, planned and scheduled to accommodate Lottery business needs. 10. UL Listing. All devices, equipment, cabinets, switches, wire, breakers, wire ways, junction boxes, connectors, batteries, battery cabinets, UPS systems, remote monitors, contacts, bypass equipment, transformers and assemblies or any other material required to complete the scope of work for this project shall be UL listed and installed per manufacturer recommendations.
