5. 1. 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.
