This dimming wiring diagram shows a typical Triac dimmable led driver installation. Check the materials that come with the led dimmer switch and the dimmable driver to make sure they match. 

The installation of the dimmable driver is almost the same as that of the non-dimmable power supply. On the DC (output) side, connect the positive and negative wires to the LED strip (or other low-voltage lighting products). On the AC (input) side, connect the neutral and ground wires directly to the power source. The live wire from the household power supply will be connected to the input of the dimmer switch, and the output of the dimmer switch will be connected to the live wire of the dimmable driver.
