Garmin Compact Reactor 40 Hydraulic Autopilot with GHC 20 and Shadow Drive Pack - Page 3

Item Description Important Considerations CCU cable Ç To extend this cable to reach the ECU, you may need to use cable extensions (sold separately) (CCU Mounting and Connection Considerations, page 1). You must connect this cable to the alarm and the Shadow Drive valve. Pump È The pump must be located within 0.5 m (19 in.) of the ECU. The cables connecting the pump to the ECU cannot be extended. Alarm É The alarm provides audible alerts from the autopilot system, and you should install it near the primary helm station (Installing the Alarm, page 6). Shadow Drive You must install the Shadow Drive valve valve (optional) properly in the hydraulic steering line, and Autopilot connect it to the CCU cable (Installing the switch (not Shadow Drive Valve, page 6). included) If your autopilot package does not include a Shadow Drive valve, you should install a manual Single Pole Single Throw (SPST) switch (not included) to disable the autopilot if necessary. Item Description Helm control À (or compatible Garmin chartplotter) Helm control Á data cable NMEA 2000  power cable NMEA 2000 à network ECU Ä CCU Å ECU power Æ cable Important Considerations A dedicated helm control is not included in all autopilot packages. If you install the autopilot without a dedicated helm control, the autopilot CCU must be connected to the same NMEA 2000 network as a compatible Garmin chartplotter to configure and control the autopilot system. You should install this cable only if you are connecting the autopilot to optional NMEA® 0183 devices, such as a wind sensor, a water-speed sensor, or a GPS device (NMEA 0183 Connection Considerations, page 8). You should install this cable only if you are building a NMEA 2000 network. Do not install this cable if there is an existing NMEA 2000 network on your boat. You must connect the NMEA 2000 power cable to a 9 to 16 Vdc power source. You must connect the helm control or compatible Garmin chartplotter and the CCU to a NMEA 2000 network using the included Tconnectors (NMEA 2000® Connection Considerations, page 2). If there is not an existing NMEA 2000 network on your boat, you can build one using the supplied cables and connectors (Building a Basic NMEA 2000 Network for the Autopilot System, page 7). The ECU must be located within 0.5 m (19 in.) of the pump. The cables connecting the ECU to the pump cannot be extended. You can mount the CCU in a non-submerged location near the center of the boat, in any orientation (CCU Mounting and Connection Considerations, page 1). Mount the CCU away from sources of magnetic interference. You must connect the ECU to a 12 to 24 Vdc power source. To extend this cable, use the correct wire gauge (Power Cable Extensions, page 5).
