Using this Blue Sea 7615 ATD Automatic Timer Disconnect is easy. First, connect it to your 12V battery and the devices you want to control. When you send a 12V signal, it'll connect the battery power to the devices. Once the signal is removed, the timer starts, and it'll disconnect the devices after the preset time. You can also set it to disconnect based on low voltage or just the removal of the 12V signal. Make sure to turn off the time and voltage options if you only want the 12V signal - based disconnect. Keep an eye on the integrated LED to know its status. When it comes to maintenance, check the terminal connections regularly to ensure they're secure. The clip - on cover helps insulate the terminals, so don't lose it. Also, be aware of the warning about the chemicals in the product.
