Item Description To the Garmin network 15 A fuse holder Red (+) Black (-) To the boat battery (10 to 32 Vdc) 30 A fuse holder Water ground connection 1 Route the power cable to the radar and the voltage converter. 2 Use crimp connectors and heat-shrink tubing to connect the power cable to the voltage converter. The radar power cable contains a 15 A fuse. You must not remove this fuse when connecting to the voltage converter. 3 Connect the voltage converter to the boat battery through the included 30 A fuse. The 30 A fuse between the voltage converter and battery is in addition to the 15 A fuse included in the radar power cable. Both fuses must be in place for the radar to function properly. 4 Connect the power cable to the POWER port on the radar. Connecting Directly to Power WARNING When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product specifications. Connecting the power cable without the appropriate fuse in place voids the product warranty. Some radar models do not require a voltage converter unit. If your model is packaged without a voltage converter, you should connect it directly to power. NOTE: Although some radar models do not require and are not packaged with a voltage converter, you can purchase one from your local Garmin dealer or go to buy.garmin.com. Using a voltage converter with these models allows them to withstand stronger winds. See the specifications section for details. 10
