Now, the color coding of the blue wire is correct; It does carry the 0 volt level. But the brown wire <b>does not</b> carry the live level, <b>nor should it be connect to the live voltage</b>, in contrary to what one might expect. The brown wire carries a 5 volt DC detection signal that can be shortened to the 0 volt level by an external switch. This means you cannot connect the output of existing switche(s) to it because those <i>will</i> feed it with live voltage.
If you're using just one switch, hook it up as a potential free switch as directed in the manual. If you're using multiple cascaded switches (hotel circuitery), you may consider connecting the input of the cascade to the 0 volt wire, instead of the usual live voltage wire. This way, you <i>can</i> connect the output of the cascade to the brown wire of the module and all your switches will be able to operate the modele. Though it's still a strange idea: Connecting the 0 voltage wire to a brown wire to make the lights switch on...
<b>Warning</b>: Do you use the trick above on heavily loaded cirquits! A heavy load draws much current through the 0 wire, making it carry a voltage by itsself and thereby lifting the 0 volt level. I'm pretty sure the module cannot handle that. I'm <b>very</b> sure the module cannot handle live voltage on it's input wire (don't ask)
