If you install the autopilot without a dedicated helmcontrol, the autopilot CCU must be connected to the sameNMEA 2000 network as a compatible Garmin chartplotter toconfigure and control the autopilot system.Detailed mounting instructions are included in the helm controlbox.Mounting the CCU1 Determine the mounting location.2 Using the CCU as a template, mark the two pilot holelocations on the mounting surface.3 Using a 3 mm (1/8 in.) bit, drill the pilot holes.4 Use the included screws to attach the CCU to the mountingsurface.NOTE: If you use mounting hardware other than the providedscrews, the hardware must be quality stainless or brassmaterial to avoid magnetic interference with the CCU.Test any mounting hardware with a handheld compass tomake sure no magnetic fields are present in the hardware.ECU InstallationMounting the ECUBefore you can mount the ECU, you must select a location anddetermine the correct mounting hardware (ECU Mounting andConnection Considerations, page 2).1 Hold the ECU in the intended mounting location and mark thelocations of the mounting holes on the mounting surface,using the ECU as a template.2 Using a drill bit appropriate for the mounting surface andselected mounting hardware, drill the four holes through themounting surface.3 Secure the ECU to the mounting surface using the selectedmounting hardware.Connecting the ECU to PowerWARNINGWhen connecting the power cable, do not remove the in-linefuse holder. To prevent the possibility of injury or productdamage caused by fire or overheating, the appropriate fusemust be in place as indicated in the product specifications. Inaddition, connecting the power cable without the appropriatefuse in place voids the product warranty.You should connect the ECU power cable directly to the boatbattery, if possible. Although it is not recommended, if youconnect the power cable to a terminal block or other source, youmust connect it through a 40 A fuse.If you plan to route the ECU power through a breaker or a switchnear the helm, you should consider using an appropriately sizedrelay and control wire instead of extending the ECU powercable.1 Route the connector-terminated end of the ECU power cableto the ECU, but do not connect it to the ECU.2 Route the bare-wire end of the ECU power cable to the boatbattery.If the wire is not long enough, it can be extended (PowerCable Extensions, page 5).3 Connect the black wire (-) to the negative (-) terminal of thebattery, and connect the red wire (+) to the positive (+)terminal of the battery.4 After you install all of the other autopilot components,connect the power cable to the ECU.Power Cable ExtensionsIf necessary, you can extend the power cable using theappropriate wire gauge for the length of the extension.Item DescriptionÀ FuseÁ Battery 9 ft.
