About this file
This is a Field Activity Report documenting preventive maintenance performed on a 93PM_UPS_100 KW REDUNDANT 3 UPM80 kVA480 uninterruptible power supply system at Fort Detrick Power House in Frederick, Maryland.
The maintenance was conducted on July 29, 2024, by Joseph Drasal of Eaton Corporation (service dispatch contact: 800-843-9433) for customer Christopher D. Zorn at Fort Detrick. The service was performed under a contract billing arrangement. The UPS system operates at 80.0 KVA and 80.0 KW capacity with serial number EP175UXX04. The inspection found the unit operating in normal system condition with no active alarms or notices upon arrival and completion. The technician downloaded historical logs, meter screens, and configuration reports; reviewed event history; and recorded system metering. All functional safety boards (FSBs) were checked, capacitors were verified within tolerance, and circuit boards were confirmed clean. Equipment readings across bypass, DC, inverter, output, and input channels were documented, showing nominal voltage and frequency parameters at 60.0 Hz with 8.6 percent load utilization. The inspection results indicate that all monitored systems passed inspection, including visual inspection, metering, room floor type, room ventilation, static switch fuses, system transfers, and communication functions. However, the report recommends battery replacement due to age; Battery 1 is an Eaton PWHR12390W4FR sealed cabinet model with a date code of 200106K83. The maintenance work consumed one hour of labor (9:00 AM to 10:00 AM) with no materials consumed during this preventive maintenance visit.
