First, let's take care of our safety! Disconnect the power by switching off the main fuse in the distribution box. Make sure that no current is flowing in the wires by placing a tester on the wires. If the light in the tester does not glow - it means that no current is flowing in the system.
There should be three wires protruding from the ceiling or two wires depending on the installation:
- Black (phase [L] ), blue (neutral [N] ), yellow-green (ground [PE] )
- Brown (phase [L] ), blue (neutral [N] ), yellow-green (earth [PE] )
- Black (phase [L] ), blue (Neutral [N] )
- Brown (phase [L] ), blue (neutral [N] )
Often, especially in older apartments, it happens that the wires have different colors or are connected incorrectly. In this case, it is worth checking in which wire the current flows. To do this, turn on the power and check with a tester where the current flows. In the future, you can mark the wire with a piece of insulating tape with the letter [L] written on it, indicating the phase wire.
Now that we know where the current is in the wire, it remains to connect the wires to the electrical block in the lamp. Make sure the current is turned off. Remove about 5mm of insulation from the wire, if the wires were previously skinned, skip this step. Connect the wires according to the markings on the wiring block. Phase wire [L] to the wire marked [L] on the terminal block, and the other wires [N] Neutral (blue) to [N] on the terminal block. PE] wire, if any, connect to the marked [PE] wire on the terminal block, if you don't have it in your installation, leave the block empty (you can insulate it for safety reasons). It is worth to mount the lamp to the ceiling, only that it is not hanging on the wires and check if everything works. If the lamp lights - (NOTE: the lamp lights better when it has light bulbs screwed in - a joke? ) - you can attach the lamp to the ceiling.
