It maybe faulty, most of those pots are made dirt cheap and fuck up alot. I have pots fail all the time, I asked a company to make them better and they told me it was too difficult even if I wanted to spend double the price to prevent failures

Connect all the dim wires to the same corresponding + and - wires comming out of the pot.
It's the same as connecting one POT but you connect 3 instead. A normal 1-10V POT can do 30 drivers or more

But there's no positive and negative. As per the manual the wires are zero line, live line and, L OUT

I'm talking about the dimmer, not the driver. Of course I understand that the MeanWell driver has a positive DIM+ and a negative DIM- wire. But where do I connect the wires with the dimmer?

This is the dimmer instructions:

Usage: First connect the load and signal lines, then connect the AC input lines.
1. N is zero line
2. L IN as Live Line Input
3. L OUT is a live-line output

But it doesn't tell me which one is positive, which one is the negative, and what do I do with the third connector. I have no idea what is a "zero line" etc.

Here's my drivers setup:

I also bought another dimmer but the circuit board is different, and it came without instructions:

Thanks for your help

Are you having trouble with the AC side or the 1-10V side?

I'm just trying to figure out where I have to connect the dimming wires of the Meanwell Driver
Gray Dim+
and Black Dim-
