Color Code according to DIN VDE 0815

	a-conductor	side circuit 1
	b-conductor
	a-conductor	side circuit 2
	b-conductor

The conductors of 5 star quads of a sub unit are counted according to the sequence of basic colors:
Quad 1: basic color of all conductors red
Quad 2: basic color of all conductors green
Quad 3: basic color of all conductors gray
Quad 4: basic color of all conductors yellow
Quad 5: basic color of all conductors white

The marker of units are identified with a red helix, the others with white or uncolored. The quads of sub units are counted according to the sequence of basic colors. The units are counted continuously through all layers beginning in the inner layer.

Installation Cables
J-Y(St)Y. . .Lg
2-paired installation cables are stranded to a star quad.

circuit 1 a-conductor red, b-conductor black
circuit 2 a-conductor white, b-conductor yellow

4- and multi-paired installation cables
a-conductor of 1. pair in each layer is red, other pairs are white
b-conductor blue, yellow, green, brown, black in continuous repeat

Counting: from outside to inside

The insulating conductors are identified with different basic colors which are repeated in each unit.

Each unit is assigned to one group of ring. All conductors in each unit are marked with colored rings and ring-groups.
Counting direction in all units is from inside to outside.
