Expanded operating
temperature
Specifications
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 in temperatures as low as 5°C and as high as 40°C.
For temperatures 35°C to 40°C, derate maximum allowable temperature by 1°C per 175 m (1°F per 319 ft)
above 950 m (3,1171 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–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 (1°F
per 228 ft) above 950 m (3.117 ft).
NOTE:
When operating in the expanded temperature range, the performance of the system may be impacted.
NOTE:
When operating in the expanded temperature range, ambient temperature warnings may be reported on the LCD panel
and in the System Event Log.
Expanded operating range
•
The operating temperature is specified for a maximum altitude of 950 m for expanded operating range.
