Hello,

Is it possible that you (unintentionally or not) unplugged/replugged the Mitras Lightbar cable on the ProfiLux side or on the splitter side (or even unplugged/replugged the Lightbar from the Splitter) WHILE the splitter power supply was running?

Yes. It is a problem?

PS I have a new splitter (not unpacked).

Yes, this is a problem because, as stated in the documentation, it can damage the Profilux and/or the Lightbar(s). It is essential to interrupt the power supply before connecting/disconnecting the Mitras communication cables.
