Particulate contamination Specifications
NOTE: This condition applies to data center and
non-data center environments.
Table 24. Gaseous contamination specifications
Gaseous contamination Specifications
Copper coupon corrosion rate <300 Å/month per Class G1 as defined by ANSI/
ISA71.04-1985.
Silver coupon corrosion rate <200 Å/month as defined by AHSRAE TC9.9.
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.

Standard operating temperature
Table 25. Standard operating temperature specifications
Standard operating temperature Specifications
Continuous operation (for altitude less than
950 m or 3117 ft)
10°C to 35°C (50°F to 95°F) with no direct sunlight on the
equipment.
GUID-E8CDC6EA-0355-4E26-8C90-8FD8741EC068
Expanded operating temperature
Table 26. Expanded operating temperature specifications
Expanded operating temperature Specifications
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.
