merlin gerin mcb and fault indicator switch

[ach69uk]

i have a merlin gerin C60 2A MCB and a fault indicator switch in front of me i have tried to put the two together but the indicator switch will not connect to the mcb i know it may seem daft but i thought these things was a plug and play kind of thing i have removed the retangular small plate of the mcb for one of the white pins to be inseterted from the fault switch , but the black pins on the fault switch prevent it from fastening it to the mcb


does anyone know if there are suppose to be removed or not or if i have something missing to this

photos of the fault indication switch and the mcb are on this thread too

Should just clip on to the left hand side of the c60 mcb.

i know , but those black pins dont seem to fit anywhere , they dont push in nothing
