05/04 AWB2528-1508GB Connecting the power supply j Applies to easy-AC devices with a power supply greater than 24 V AC: h Attention! A short current surge will be produced when switching on for the first time. Do not switch on easy by means of reed contacts since these may burn or melt. • The voltage terminals for phase L and neutral conductor N have been reversed. • This enables the easy interface (for memory card or PC connection) to have the full connection voltage of the phase conductor (100 to 240 V AC). • There is a danger of electric shock if the connection at the easy interface is not properly connected or if conductive objects are inserted into the socket.
