The temperature inside the terminal box may not
exceed 70°C. Consequently, if the compressor is
installed in an enclosure, precautions must be
taken to avoid that the temperature around the
compressor and in the terminal box would rise
too much. The installation of ventilation on the
enclosure panels may be necessary. If not, the
electronic protection module may not operate
properly. Any compressor damage related to this
will not be covered by Danfoss warranty. In the
same manner, cables must be selected in a way
to insure that terminal box temperature does not
exceed 70°C.
