TECHNICAL SPECIFICATIONS
4.1 Weather conditions
The 20/50kVA FIEM has been designed to operate under the following operating conditions:
Atmospheric temperature between
Relative humidity between
Maximum working altitude
Forced ventilation and cooling. The inlet and outlet of refrigeration air must be free of any
obstacles in order to allow the unit to be ventilated correctly. The ventilation system must be
controlled by means of a current relay and will only come into operation above a number of
predefined values.
