of the unit
0-40°C (32-104°F) at nominal current.
Over 40°C use the derating curve (max 50°C).
-25°C to 70°C, -13°F to 158°F
Don't install at direct sun light,
where there are conductive dust, corrosive gas,
vibration or water and also in salty environmental.
Up to 1000 meter over sea level.
For higher altitude reduce the nominal current
of 2% for each 100m over 1000m
From 5 to 95% without condense and ice
