IP54 zone: Heat sink outside the housing
The protection class IP54 can only be achieved when the device is properly
installed.
For proper installation, a suitable IP54 seal
(=> „4.3.2 Seal for IP54-ready devices“) must be installed between heat sink
and housing (e.g. control cabinet wall).
The tightness must be checked after the installation. If properly installed, the
separation to the housing corresponds to degree of protection IP54.
IP20 zone: Device inside the housing
This part is intended for the installation in a suitable housing for the required
degree of protection (e.g. control cabinet).
The power connections are excluded => „3.1.1 Climatic environmental condi-
tions“.
