Optimal battery performance: 25°C (77°F)
Storage Temperature
UPS with battery modules: –20°C to +40°C (–4°F to 104°F)
UPS without batteries: –40°C to +60°C (–40°F to 140°F)
Relative Humidity
5–95% noncondensing
Operating Altitude
Up to 3,050 meters above sea level (10,000 ft)
The maximum operating ambient temperature decreases 1°C
per 300m above 1525m (2°F per 1000 ft above 5000 ft)
Non-Operating Altitude
Up to 12,200m above sea level (40,000 ft)
Ventilation
The air around the UPS must be clean and free of dust,
corrosive chemicals, and other contaminants. The Eaton 9PXM
UPS uses internal fans to circulate the air for cooling. The air
must be free to circulate around the UPS and battery cabinet(s).
Do not operate the UPS in a sealed room or container.
Audible Noise
Less than 67 dBA
