3.1 Functional description

the corresponding outlet filter(s) is used

ventilate the enclosure and protect
temperature-sensitive components. This is
achieved via the direct infeed of ambient
air, the temperature of which must be less
than the admissible enclosure interior
temperature. The system is fitted into
prepared cut-outs.
