This document is a Preventive Maintenance (PM) service report for a Uninterruptible Power Supply (UPS) system at Creech Air Force Base, Building 1005. The service was requested on an unspecified date and performed by a technician named Ryan Seaberg, who can be reached at (702) 404-0740.

The UPS system is a Schneider Electric Galaxy VX model with a 750 KVA capacity, featuring C&D Technologies UPS12-600MR batteries (40 batteries per string, dated December 2019). The inspection included comprehensive voltage checks, battery testing, and performance verification across all four battery strings, with all components passing inspection. The technician documented detailed mOhm resistance and voltage readings for each individual battery, along with system-wide AC input/output voltage checks, battery voltage measurements, and kW load calculations. The facility requires 160 replacement batteries (part number 12HX540-FR) and 26 battery jumpers as part of the maintenance service. The UPS system status is marked complete and on-line, with load on maintenance by-pass indicated as "No." Temperature readings during inspection were 74°F in the room, 75°F in the battery cabinet, and 75°F for the batteries themselves. All diagnostic tests passed, including air filter inspection and fan operation verification.
