Summary of Contents for Garmin Boat Switch

  • Page 1 Device ™ Follow these steps to set up a Garmin Boat Switch device on the vessel. Additional information and instructions are contained in this document for your reference. You should contact Garmin product support or your Garmin field service engineer (FSE) for assistance or if you have any questions.
  • Page 2: Mounting Considerations

    Mounting Considerations Selecting the correct mounting location is critical to optimize the performance of the Garmin Boat Switch device. When selecting a mounting location, observe these considerations. • You must mount the device in an accessible location. ◦ All of the switches on this device can be activated by pressing buttons on the device directly. Because of this, the device must be accessible in case there is an issue with switching using the chartplotter.
  • Page 3 NOTICE Do not use the Garmin Boat Switch device as a template when drilling the mounting holes because drilling through the mounting holes may damage the device and void the warranty.
  • Page 4: Connection Considerations

    Connection Considerations You should carefully plan the layout of the device, the power wiring, the NMEA 2000 network, and all switched devices before making any connections. When making connections, observe these considerations. • This device supports a maximum of 50 A total for all active channels. When planning switched connections, consider the power needs of all potential load combinations to ensure that the total active load does not exceed 50 A when in use.

    WARNING The wiring (not included) from the power source to the positive terminal of the Garmin Boat Switch device must run through a 50 A circuit breaker or in-line fuse (not included) as close to the power source as possible. You must connect the positive wire to the fuse or circuit breaker.
  • Page 17: Configuring The Device

    Some digital switches must be configured through a Garmin chartplotter before use. You must connect all switches and switched devices to the Garmin Boat Switch device and power before configuring them using a Garmin chartplotter connected to the same NMEA 2000 network as the Garmin Boat Switch device.
