Table 1. Expanded operating
temperature specificationsWhen the system is in continuous operation, the
expanded operating temperature ranges 5°C to 40°C at 5% to 85%
RH with 29°C dew point. 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 35°C to 40°C, derate maximum allowable temperature by 1°C per 175 m above
950 m (1°F per 319 ft). When the system is operating at < 1% of
annual operating hours, the expanded operating temperature is -5°C to 45°C at 5% to 90% RH with 29°C dew point. 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 40°C to 45°C, derate maximum allowable
temperature by 1°C per 125 m above 950 m (1°F per 228 ft).
Expanded operating temperature
Specifications
Continuous operation
5°C–40°C at 5% to 85% RH with 29°C dew point.
NOTE Outside the standard
operating temperature (10°C–35°C), the system can operate continuously
in temperatures as low as 5°C and as high as 40°C.
For temperatures 35°C– 40°C, derate maximum allowable
temperature by 1°C per 175 m (1°F per 319 ft) above 950 m (3,1171
ft).
≤ 1% of annual operating hours
-5°C–45°C at 5% to 90% RH with 29°C dew point.
NOTE Outside the standard
operating temperature (10°C–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 40°C– 45°C,
derate maximum allowable temperature by 1°C per 125 m (1°F per 228
ft) above 950 m (3.117 ft).
NOTE When
operating in the expanded temperature range, the performance of the
system may be impacted.
NOTE When operating in the
expanded temperature range, ambient temperature warnings may be reported
on the System Event Log.
