This is a Preventive Maintenance (PMV) Annual Service Report for a Vertiv UPS system (model 53S30HCFR2000QU, serial number M21GBF0001) installed at NIST Boulder CO Olgoonik facility in Boulder, Colorado. The report documents a service visit conducted on 9/20/2024 by attending engineer Alex Metz for customer Michael Parenteau.

The UPS unit is a 30 kVA, 30 kW system with 208V nominal input voltage, configured as a single unit with 1.63 Ah battery capacity at 8 hours, one string of 40 jars, and an Earth to Neutral Voltage of 0V. The equipment is located in the basement and was installed in 2021. The visit summary indicates the unit arrived online with no alarms or faults and departed fully operational. Pre-work health and safety assessment identified no hazards. All required preventive maintenance activities were completed, including environmental, UPS mechanical, UPS control, and measurements and operational testing. The environmental assessment confirmed unit room temperature at 22°C, battery ambient temperature maximum of 23°C and minimum of 23°C, with sufficient ventilation and cleanliness. Operational status showed the unit is online with no alarms. The report documents comprehensive mechanical, power circuit, and control system inspections, along with detailed electrical measurements for both input and output phases. The findings indicate no issues at the time of the visit, with the annual preventive maintenance complete and the unit online with no alarms. No customer actions were required.
