All work to be carried out without mains supply (230 V AC) or any batteries connected. Route the connecting cables into
the control panel housing at the top. Connect all connecting cables according to the wiring diagram and make sure that
they are correctly connected. Incorrect connections or figure or colour mix-ups can lead to incorrect function of the
control panel or of the external components. The notes and installation directives in the technical documentation are
always to be observed.
