NOTE: Applies to data center and non-data center environments.

Corrosive dust

NOTE: Applies to data center and non-data center environments.

Gaseous contamination

Air must be free of conductive dust, zinc whiskers, or other conductive particles.

•Air must be free of corrosive dust.

•Residual dust present in the air must have a deliquescent pointless than 60% relative humidity

NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.

Copper coupon corrosion rate	<300 Å/month per Class G1 as definedby ANSI/
	ISA71.04-1985.
Silver coupon corrosion rate	<200 Å/month as defined by AHSRAETC9.9.
Expanded operating temperature

NOTE: When operating in the expanded temperature range, system performance may be impacted.

NOTE: When operating in the expanded temperature range, ambient temperature warnings may be reported on the LCD and in the System Event Log.

Continuous operation

< 1% of annual operating hours

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 down to 5°C or 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).

–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.
