How do I connect an L N PE lamp to a Fibaro Smart Home system using brown, black and grey PE wires?

Hi,

I’m not an electrician and I have no experience with electrical installations, so please bear with me.

Up until now, fitting lights has been straightforward for me. There were three wires coming out of the ceiling: yellow-green, blue and brown, so I had no trouble connecting the light.

In my new flat, the situation is completely different. I think I have a staircase light switch, and on top of that, the whole system is integrated with the Fibaro Smart Home.

A junction box protrudes from the ceiling, to which four wires are connected:

* yellow-green,
* brown,
* black,
* grey.

My light fitting has standard terminals: L, N and PE.

Could someone explain how to correctly identify these wires and connect the light fitting? In a Smart Home/Fibaro system, might the wire colours be used differently from the standard? I wouldn’t want to damage anything or create a hazard.



Thank you in advance for your help.

It depends on the installer. :>

Please explain exactly how it’s connected.
