2.10 Environmental specifications 2.10.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 65°C (149°F) within the operating ambient conditions. Above 1,000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet. Operating 5° to 55°C (41° to 131°F) Nonoperating -40° to 65°C (-40° to 153°F) 2.10.2 Temperature gradient Operating 20°C per hour (68°F per hour max), without condensation Nonoperating 30°C per hour (86°F per hour max) 2.10.3 Humidity 2.10.3.1 Relative humidity Operating 5% to 90% noncondensing (30% per hour max) Nonoperating 5% to 95% noncondensing (30% per hour max) 2.10.3.2 Wet bulb temperature Operating 33°C (91.4°F max) Nonoperating 40°C (104°F max) 2.10.4 Altitude Operating -192.12 m to 3,048 m (-650 ft to 10,000+ ft) Nonoperating -304.8 to 12,192 m (-1,000 ft to 40,000+ ft) Momentus 42 Product Manual, Rev.
