Expanded operating temperature
Specifications
For temperatures between 35°C to 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 appliance 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, appliance performance may be impacted.
NOTE:
When operating in the expanded temperature range, ambient temperature warnings may be reported in the System
Event Log.
