Specification Value
System inlet temperature —
Operating 10° to 35°C (50° to 95°F) at sea level
with an altitude derating of 1.0°C per
every 305 m (1.8°F per every 1000 ft)
above sea level to a maximum of 3050
m (10,000 ft), no direct sustained
sunlight.
Maximum rate of change is 10°C/hr
(18°F/hr). The upper limit may be
limited by the type and number of
options
installed.
System performance may be reduced if
operating with a fan fault or above 30°C
(86°F).
Non-operating
-30° to 60°C (-22° to 140°F). Maximum
rate of change is 20°C/hr (36°F/hr).
Relative humidity (non-condensing) —
Operating
10 to 90% relative humidity (Rh), 28°C
(82.4°F) maximum wet bulb
temperature, non-condensing.
Non-operating 5 to 95% relative humidity (Rh), 38.7°C
(101.7°F) maximum wet bulb
temperature, non-condensing.
Altitude —
Operating
3050 m (10,000 ft). This value may be
limited by the type and number of
options installed. Maximum allowable
altitude change rate is 457 m/min
(1500 ft/min).
Non-operating 9144 m (30,000 ft). Maximum
allowable altitude change rate is 457
m/min (1500 ft/min).
Acoustic noise Listed are the declared A-Weighted
sound power levels (LWAd) and
declared average bystander position
A-Weighted sound pressure levels
(LpAm) when the product is operating in
a 23°C ambient environment. Noise
emissions were measured in accordance
with ISO 7779 (ECMA 74) and
declared in accordance with ISO 9296
(ECMA 109).
