Garmin GMR 2524 xHD2 Open Array Radar and Pedestal Installation Instructions - Page 3

Installing the Antenna Before you can install the antenna on the radar, you must securely mount the pedestal (Mounting the Radar, page 2). 1 Remove the protective cover from the waveguide on the top of the pedestal. 2 Align the waveguide on the pedestal with the socket on the À bottom of the antenna , and slide the antenna onto the Á pedestal. • The power cable should be installed as close to the battery source as possible. ◦ If it is necessary to extend the power cable, the appropriate gauge of wire must be used (Power Cable Extensions, page 4). ◦ Incorrectly extended runs of cable may cause the radar to malfunction due to insufficient power transmission. Connecting to Power Through the Voltage Converter 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. In addition, connecting the power cable without the appropriate fuse in place will void the product warranty. 3 Secure the antenna to the pedestal using the included hex bolts and spring washers . Â Ã 4 Torque the hex bolts to 0.81 kgf-m (70 lfb-in. [6 lbf-ft.]) to fasten the antenna to the pedestal without damaging the antenna or the mounting hardware. NOTICE Do not reuse any voltage converters from previous Garmin radar models, or third party voltage converters. Using any converter other than one included with the radar may damage the radar or prevent it from turning on. Some radar models require a voltage converter unit to properly power the device. If your model is packaged with a voltage converter, it must be installed in order for your radar to function. If your model is not packaged with a voltage converter, connect the power cable directly to the boat battery (Connecting Directly to Power, page 4). When installing the voltage converter for an applicable radar model, observe these considerations. • The voltage converter requires an input voltage of 10 to 32 Vdc. • It is recommended to install the voltage converter as close as possible to the power source. • Connecting the power cable for the voltage converter directly to the battery is recommended. If it is necessary to extend the cable, the appropriate gauge of wire must be used for the length of the extension (Power Cable Extensions, page 4). Cable Considerations It may be necessary to drill 31.7 mm (1 ¼ in.) holes for routing the power or network cable. The provided rubber cable grommet can be used to cover a cable installation hole. • The grommet does NOT provide a waterproof seal. To make the grommet waterproof, marine sealant must be applied. • If needed, the grommet can be trimmed to route both the power and the network cable through the same hole. • Additional cable grommets can be purchased from Garmin or a Garmin dealer. When installing the power and network cables, you should observe these considerations. • Cutting the Garmin Marine Network cable is not recommended, but a field install kit can be purchased from Garmin or a Garmin dealer if cutting the network cable is necessary. • To ensure safety, appropriate tie-wraps, fasteners, and sealant should be used to secure the cable along the route and through any bulkheads or the deck. • Cables should not be run near moving objects and high-heat sources or through doorways and bilges. • To avoid interference with other equipment, power and network cables should not be run next to or parallel to other cables, such as radio antenna lines or power cables. If this is not possible, the cables should be shielded with metal conduit or a form of EMI shielding. Item Description To the Garmin Marine Network 7.5 A fuse holder Red (+) Black (-) To the boat battery (10 to 32 Vdc) 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 7.5 A fuse which should not be removed when connecting to the voltage converter. 3 Connect the voltage converter to the boat battery through a 15 A, slow-blow fuse (not included). The 15 A fuse (not included) between the voltage converter and battery is in addition to the 7.5 A fuse included in the radar power cable. Both fuses must be in place for the radar to function properly. GMR 420/620/1220/2520 xHD2 Series Installation Instructions 3
