Table 27. Expanded Operating Temperature
Condition
Temperature
Continuous operation
5 °C to 40 °C at 5% to 85% RH with 29°C dew point.
NOTE:
Outside the standard operating temperature (10°C to 35°C), the system
can operate continuously down to 5°C or as high as 40°C.
For temperatures between 35°C and 40°C, derate maximum allowable temperature by
1°C per 175 m above 950 m (1°F per 319 ft).
< 1% of annual operating hours
–5°C to 45°C at 5% to 90% RH with 29°C dew point.
NOTE:
Outside the standard operating temperature (10 °C to 35 °C), the system
can operate down to –5°C or up to 45°C for a maximum of 1% of its annual
operating hours.
For temperatures between 40°C and 45°C, derate maximum allowable temperature by
1°C per 125 m above 950 m (1°F per 228 ft).
