The package provides a fuse and a Power Entry Module. The manual only tells me to snap in the Power Entry Module. It seems that the manual does not say anything about the fuse (just finishing the chassis, maybe somewhere later).
Not sure if the Power Entry Module has already got a fuse inside it?
If not, how to open the fuse holder to insert the fuse. I tried a little bit to open the fuse cover with my nail, but it seemed quite difficult to open. So I stopped there just to avoid damaging anything. Should I try really hard or even use some tools, such as a screw-driver, to open the cover?
