DANGER! Never connect mains voltage (230 V) or other external voltages to the extension inputs. Connecting an external voltage jeopardizes the electrical safety of the entire KNX/EIB system (SELV/no galvanic isolation)! Persons may be exposed to danger, equipment and facilities may be destroyed.

 

Ensure a distance of at least 4 mm between the low voltage lines (bus and extension inputs) and the load lines (230 V).
