Corrosive dust
• Air must be free of corrosive dust.
• Residual dust present in the air must have a
deliquescent point less than 60% relative humidity.
NOTE:
This condition applies to data center and
non-data center environments.

Expanded operating temperature
Specifications
≤
10% of annual operating hours
5°C to 40°C (41°F to 104°F), avoiding direct sunlight on
the equipment.
NOTE:
Outside the standard operating temperature
(10°C to 35°C / 50°F to 95°F), the system can operate
for a maximum of 10% of its annual operating hours
in temperatures as low as 5°C (41°F) and as high as
40°C (104°F).
For temperatures between 35°C and 40°C (95°F
and 104°F), de-rate maximum allowable
temperature by 1°C per 175 m above 950 m (1°F
per 319 ft).
