Tunze cables 1,2 - Diffrent

[wrang]

I wonder how i can see the diffrent in the cables called Tunze 1 and Tunze 2

the recently shipped cables have a lable
if you have a cable without lable and you have unpacked it already then there is only one way: test it and watch if the pump reacts on L1 (L3) or L2 (L4)
