Iris Power board not soldered

According to the 3DR PDF on replacing Iris’s motors the connections are soldered to the power board.

However i just opened my Iris to replace a motor and the connections are not soldered and I’m not sure how to unplug/replug. See attached picture.

Any ideas how I can do it?

Cheers

They are bound to the PCB using clamps. They are very resistant to vibration. If you need to remove a motor you can solder the cable to the board instead.

using a pliers you can open and remove the clamps to have access to the board pads where you can solder the motors.
