3.8 Operation Outdoor -33 C – +40 C
This Environmental class corresponds in full to Operation Outdoor -33 C -
+45 C with the exception of the upper temperature limit.
3.9 Operation Outdoor -33 C – +45 C
The severity of the requirements is in conformity with: IEC 721-3-4 classes
4K2/4Z5/4Z7/4B1/4C2(4C3)/4S2/4M5. and ETS 300 019-1-4 Class 4.1.
"NON-WEATHERPROTECTED location", except for the temperature range
which is extended to +45 C.
This clause refers to the environment which an RBS for outdoor non-weather
protected location endures.
The figures below refer to the environment that surrounds the cabinet, and the
temperature is the shaded air temperature.
3.9.1 Climatic Conditions
The severity of these requirements is in conformity with: IEC 721-3-4 classes
4K2/4Z5/4Z7. and ETS 300 019-1-4 Class 4.1. In addition to this Ericsson
demands more rigorous values than stated by IEC and ETSI above.
