Expanded operating temperature Expanded operating temperature Continuous operation ≤ 1% of annual operating hours Specifications 5°C-40°C at 5% to 85% RH with maximum 29°C dew point. NOTE: Outside the standard operating temperature (10°C-35°C), the system can operate continuously in temperatures as low as 5°C and as high as 40°C. For temperatures between 35°C-40°C, derate maximum allowable temperature by 1°C per 175 m above 950 m (1°F per 319 ft). -5°C-45°C at 5% to 90% RH with maximum 29°C dew point. NOTE: Outside the standard operating temperature (10°C-35°C), the system can operate down to - 5°C-45°C for a maximum of 1% of its annual operating hours. For temperatures between 40°C-45°C, derate maximum allowable temperature by 1°C per 125 m above 950 m (1°F per 228 ft). NOTE: When operating in the expanded temperature range, system performance may be impacted. NOTE: When operating in the expanded temperature range, ambient temperature warnings may be reported in the System Event Log. Operating temperature derating specifications Table 15. Operating temperature Operating temperature derating < 35°C (95°F) Specifications Maximum temperature is reduced by 1°C/300 m (1°F/547 ft) above 950 meters (3,117 ft) 35°C-40°C (95°F-104°F) Maximum temperature is reduced by 1°C/175 m (1°F/319 ft) above 950 meters (3,117 ft) > 45°C (113°F) Maximum temperature is reduced by 1°C/125 m (1°F/228 ft) above 950 meters (3,117 ft) 16 Technical specifications
