however be aware that the suitable fuse / breaker rating is dependent on the number of devices

Implementation — direct connection to battery
• Where connection to a power distribution panel is not possible , the power cable supplied with
your product may be connected directly to the vessel's battery, via a suitably rated fuse or breaker.
• The power cable supplied with your product may NOT include a separate drain wire. If this is the
case, only the power cable's red and black wires need to be connected.
• If the power cable is NOT supplied with a fitted inline fuse, you MUST fit a suitably rated fuse or
breaker between the red wire and the battery's positive terminal.
• Refer to the inline fuse ratings provided in the product's documentation.
• If you need to extend the length of the power cable supplied with your product, ensure you
observe the dedicated Power cable extensions advice provided in the product's documentation.
