hygena extractor fan?

Hello,

my hygena APM2591 extractor fan stopped workiing. Pretty sure the PCB/switches have gone. I purchased a new PCB however it looks slightly different to the old one. The new one has a block at one end with N and L maked on it, the old one just had the wires directly soldered onto the PCB and no block at the end marked N and L.

Should i ignore the 'block' on the new one and just solder as before or do i solder the earth onto the same place as the existing board and then put L and N into the block on the PCB? Or just solder same into same places as per current PCB board? (Maybe the block is so the pcnb fits multiple models?)
