+10 °C to +35 °C (50 °F to 95 °F) with a maximum
temperature gradation of 10° per hour.
Note: For Altitudes above 2950 feet , the maximum
operating temperature is derated 1 °F/550 ft.
All temperature ratings shown are for sea level. An
altitude derating of 1 °C per 300 m (1.8 °F per 1,000 ft)
to 3048 m (10,000 ft) is applicable. No direct sunlight
allowed.
-30 °C to 50 °C (-22 °F to 122 °F)
–40 °C to 65 °C (–40 °F to 149 °F)
ATTENTION
All temperature ratings described previously
are for sea level. An altitude derating of 1 °C
per 300 m (1.8 °F per 1,000 ft) to 3048 m
(10,000 ft) is applicable. Direct sunlight is not
allowed.

maximum dew point
5% to 95% RH with 33 °C (91 °F) maximum dew
point. Atmosphere must be non-condensing at all
times.
ATTENTION
Storing maximum humidity of 95% is based
on a maximum temperature of 45 °C (113
°F). Altitude maximum for storage
corresponds to a pressure minimum of 70
KPa.
