With that lever you open the electric door.
Further down the table you will find a key.
With that key you will open the door to the beginning.
inside you will find a piece like a gear with that you go to the place where the electric door table is next to it you will put the gear

After putting the gear in place, you'll unlock the exoskeleton. When you get it, you'll have to hit a wolf face that is scattered around the map. Here I show you where they are.
