You dont. your generator can be connected to some energy aux. (dont remember the name) to create more power. Control devices must be connected to a mainframe.
They connect automaticly when placed in the same room.
Yeah you need to have a mainframe/arcane control system to make it work. Sadly that is 150k 
Ok so far we have;
Rooms: Entrance, Power, Workshop, Control
Devices: Basic Generator, Basic Workbench, Basic control station.
Power generated=100
Control generated=10
However, I cannot seem to connect the workbench/control box to the power supply. It says it has 2 allowed connection:0 connected.
So how do we go about hooking them all up??
