Particulate contamination Specifications

NOTE: This condition applies to data center and non-data center

environments.

Table 12. 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 13. 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.

Humidity percentage range 10% to 80% Relative Humidity with 26°C (78.8°F) maximum dew point.

Expanded operating temperature

Table 14. 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 dry

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

Less than or equal to 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 maybe reported on the LCD

panel and in the System Event Log.

Expanded operating temperature restrictions
