ENVIRONMENTAL CONDITIONS
A.
Ambient Temperature 1.
Operating: The ambient temperature range, when UPS is operational, shall be from 32°F to 104°F (0°C to 40°C). There shall not be any degradation in the performance when operating in this range. Automatic derating shall occur for operation in higher ambient temperatures. 2. Storage: 5°F to 104°F (-15°C to 40°C). B. Relative Humidity 1. Operating: 0 to 95% non-condensing. 2. Storage: 0 to 95% non-condensing. C. Altitude: 10,000 ft. (3,000m) max., without power derating when operated within the temperature specified in Section 1.4, Item A. Ambient temperature shall be derated 9°F (5°C) for each additional 1600 ft. (500m) above 10,000 ft. (3,000m). D. Audible Noise: The audible noise of the UPS shall be less than 55dBA max when measured at 1 meter from front, sides, or rear.
