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).
