+5
Altitude up to 3050m (10,000ft)
Humidity up to 95% relative humidity to 40
protected from temperature extremes which may cause

restricted. The ambient temperature (outside the cabinet) must be less
than the maximum operating temperature of the instrument by 4
every 100 watts dissipated in the cabinet. If the total power dissipated in
the cabinet is greater than 800 watts, then forced convection must be
used.
