Just wondering...I am finally setting up the backup I got with the pumps. But for the life of me can not figure it out. I dont remember having a seperate power supply for it. And its been so long I wouldnt really remember anyways. I thought you just to the power supply from the wave controller and plugged that into the battery backup. Then connected the out port on the battery to the wave controller. But when I do that it flashes green saying its on battery backup power.
