1	DIN Rail enclosure, consisting of: black bottom white case white front panel 5 pcs terminal guards for screw terminals 1 pcs KNX cover 1 pcs terminal guard for heat-flow 1 pcs terminal guard, closed
1	MiniUSB socket, vertical
2	micromatch socket, 2x3 pin
1	micromatch socket, 2x8 pin
1	micromatch socket, 2x4 pin
2	micromatch plug, 2x3 pin
1	micromatch plug, 2x8 pin
1	micromatch plug, 2x4 pin
1	pcs of flat cable
1	PCB enclosure cover, printed and drilled
1	M0dularis+ controller PCB
1	Frontend PCB, 8 Buttons, 8 LEDs
1	Application PCB, 8x BiRelay
1	MicroBCU with pinheaders

Take the flat cable and cut the following lengths and ensure, each cut part has it's own "red wire":

• xx cm, 6 wires
• xx cm, 8 wires

The result shoud look like this:
