New Elite Foreman Install (what is the A cable?) (solved, the masso screen power cable)

I just received my Elite Foreman after a nine week wait. Today I installed everything. Odd there was one cable left over labeled A but there was no reference of it in the PDF installation document I have. The big issue is the Masso controller will not turn on. The button lights up on the power supply and each of the 4 steppers are showing red and green lights lit. I went through Emergency button sequence correctly but that has no affect. When I tried to call Support I got a message saying use email. Is support only through email?

ā€œAā€ should be the power cable for the controller. Connects to the power box, by the green button, and plugs into the masso controller next to tye cable labeled ā€œX.ā€

Found out what the A cable is for. Provides power to the Masso!! Now it works better now that it has power.
