Where should I install the 16633 Idea and 14181 Plana switches with infrared presence detectors for switching on lights?

Keep them away from heat sources and barriers like plants, furniture or columns; they should not be exposed to direct sunlight or have interior lights shining directly on them; they should be mounted 110 to 130cm above ground level if the installation is flush mounted. For higher installation, they must be installed on an adjustable supports.
