Expanded operating temperature specifications

Table 18. Expanded operating temperature

Expanded operating temperature

Specifications

Continuous operation

5°C–40°C at 5% to 85% RH with maximum 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 between 35°C-40°C, derate maximum allowable

temperature by 1°C per 175 m above 950 m (1°F per 319 ft).

≤ 1% of annual operating hours

–5°C–45°C at 5% to 90% RH with maximum 29°C dew point.

NOTE:

Outside the standard operating temperature

(10°C–35°C), the system can operate down to –

5°C-45°C for a maximum of 1% of its annual operating

hours.

For temperatures between 40°C-45°C, derate 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.
