Zusammenfassung:	Elevator drives are components that are exposed to dust and impurities. These drives typically include electronic components that need to be protected from dust and impurities. This can be achieved by placing the electronic components on a multiple layer circuit board so that they can be separated from the open space. This is provided by having a sealable opening through which the circuit board extends. Connectors to the external cables are provided outside the tight casing. The surface of the circuit board has an empty area at the sealable opening. The conductive tracks from electronic components to the connectors are arranged to layers located inside the multiple layer circuit board.
