Expanded Operating Temperature
NOTE: When operating in the expanded temperature range, ambient temperature warnings may be reported on
the LCD and in the System Event Log.
< 10% of annual operating hours 5 °C to 40 °C at 5% to 85% RH with 26 °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 40 °C for a maximum of 10% of its annual
operating hours.
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 26 °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 dry bulb temperature by 1 °C per 125
m above 950 m (1 °F per 228 ft).
