3.4 Environment conditions
Please check and consider the following environment conditions before starting the installation:
Check for the ambient temperature to be below 40°C. If it is higher, consider the
following derating:
>40°C <45°C = 10% ≥45°C <50°C = 20% ≥50°C <55°C = 30%
≥55°C = 100% (off) Ambient temperature above 40°C will affect the lifetime!
Check for the ambient temperature to be above -10°C. If it is lower, a heater must be
installed.
Hint: Ambient temperature means the temperature inside the cabinet with the RHF-
Check for the installation height to be below 1000m above sea level. If it is higher,
