Expanded operating temperature Specications
Continuous operation 5°C to 40°C at 5% to 85% RH with 29°C
dew point.
NOTE: 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 between 35°C and 40°C,
de-rate maximum allowable 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 may be reported in the System Event
Log.
