Environmental Conditions
Maximum environmental temperature at use is +50
°C; 24 hour average temperature
must not 35
°C. Lowest environmental temperature at use is –40
°C. Relative air
humidity must not exceed 50
% at maximum temperature +50
°C. Higher humidity is
allowed at lower temperature (like: 95
% at +20
°C).
Sea-level elevation must not exceed 2000 metres. When using above 1000 metres
consider lower air dielectricity and different cooling conditions.
