Using this product is a breeze. First, get your 2x8 IDC cable and connect it to the PCB. Then, mount the PCB on the DIN rail (you'll need to provide the rail yourself). After that, unscrew the terminal blocks. You can slide in your stranded or solid - core wire to connect and power your sensors, displays, or microcontrollers. As for maintenance, keep the product in a dry place. If there's dust on it, you can use a dry cloth to gently wipe it. And always double - check your connections to make sure everything is secure. Also, remember that soldering is not required, so don't try to solder the wires to the terminal blocks.
