Expanded operating temperature Specifications
For temperatures between 35°C and 40°C, de-rate maximum
allowable dry bulb 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 maybe reported on the LCD
panel and in the System Event Log.
