The Sram 11-speed Powerlink works the same way. The installation method requires standing on the pedal until it clicks into place. It clicks in with fairly easy pedal pressure.
Move the chain back onto the small chain ring, back-pedal until the masterlink is on the top portion of chain, pull the rear brake and turn the pedal forward until the masterlink clicks into place.
I've had good luck removing and re-using the link, as have others. But Sram says it's a one-time use link.
There's multiple ways to remove these.
1. Park Tool MLP-1 pliers press inward on the two rollers. Easy.
2. Some people use regular pliers at an angle, pressing on opposite plates, using the permanently connected plate ends. This video
demonstrates.
3. This worked slick: Just bend an old spoke in half with a bulge in the middle, then squeeze with pliers. It's not real critical on the bends, just eyeball it. (I first tried with coathanger wire, but that's a little too thick.) I'm sure that bike shops have junk spokes if you don't have any.
At 0:10, it shows the link removal. I always do this on the bottom portion of the chain, not this top side.
At 1:18, the video sort of shows how to bend the tool. And you have to cut off the J bend spoke end.
Edit -- here's my homemade tool, complete with tape flag so I don't throw it out accidentally:
