Some of the USB plugs on Victron cables are excessively long, which can pose a challenge when attempting to fit them into a Wall mount box alongside a Color Control GX. To address this issue, we recommend using a USB extension cable, specifically designed to provide additional flexibility and ensure a secure connection. This extension cable is available in a convenient 0.3-metre length, allowing for easy integration into your setup without compromising on functionality or aesthetics. By utilising this extension cable, you can effectively overcome the space constraints within the Wall mount box, ensuring a neat and professional installation of your Victron system components.
