Storage Temperature
–40 °C to 65 °C (–40 °F to 149 °F) with a maximum
temperature gradation of 20 °C per hour.
Standard Operating Temperature
Continuous operation: 10 °C to 35 °C at 10% to 80%
relative humidity (RH), with 26 °C max dew point. De-
rate maximum allowable dry bulb temperature at 1 °C
per 300 m above 900 m (1 °F per 550 ft).
Expanded Operating Temperature
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 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).
