One of the black wires will be a switched live, the other neutral.
Same applies to the yellow and blue wires, which are probably for an extractor fan.

The two switched live wires go into the L terminal.
The two neutral wires go into the N terminal.

To identify which is what, you will need a multimeter.

One of those blacks may not be a neutral. It may be a switched live.

Is there a red sleeve on either of the blacks? If not, you are going to need a test meter.
Also, tell us what colour wires are connected to which terminals in the fan.

Edit: curse you Flameport. Too quick again
