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 between 35°C and 40°C, de-rate 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, de-rate 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 on the LCD
panel and in the System Event Log.
