Installation Procedures; Mounting The Ccu - Garmin GHP 10V Installation Instructions Manual

After you have completely planned the GHP 10V installation on your boat, and have satisfied all the mounting and wiring considerations for
your particular installation, you can begin mounting and connecting the components.
Installing the Course Computer Unit (CCU)
Install the CCU by mounting it to your boat, connecting it to the Autopilot Gateway and to a NMEA 2000 network, and wiring it to power, to
the alarm buzzer, and to the yellow CCU signal wire on the GHC 10.

Mounting the CCU

Mount the CCU on the boat by using the included bracket. The CCU bracket has two portions: the mounting portion and the securing portion.
Install the mounting portion on the mounting surface, and secure the CCU in the bracket with the securing portion.
When mounting the CCU:
• Mount the CCU in the forward half of the boat, no higher than 10 ft. (3.05 m) above the waterline.
• You can mount the CCU below the waterline, as long as it is not in a location where it will be submerged or exposed to wash-down.
• Mount the CCU bracket on a vertical surface or under a horizontal surface, so that the connected wires hang straight down.
• Do not mount the CCU near magnetic material, magnets (speakers and electric motors), or high-current wires.
• Mount the CCU at least 24 in. (0.6 m) away from movable or changing magnetic disturbances such as anchors, anchor chain, wiper
motors, and tool boxes.
• Use a handheld compass to verify the absence of magnetic interference. If the handheld compass does not point north when you hold it
in the location you want to mount the CCU, then there is magnetic interference. Choose another location and test again.
• If possible, mount the CCU within 9
Gateway, use a NMEA 2000 drop cable up to 20 ft. (6m) long (not included) to extend the cable. Do not connect the CCU cable to a
NMEA 2000 network.
To mount the CCU bracket:
1. Determine the best location for the CCU on your boat. Use a handheld compass to be sure
that the location is free of magnetic interference.
2. Determine the correct type of screws for the mounting surface. Mounting screws are included
with the CCU, but you may need to provide different screws or use bolts if the supplied
screws are not suitable for the mounting surface.
3. Use the mounting template provided on
opening at the bottom, because the CCU cables must hang straight down. Tape the template
to the mounting location.
4. Drill pilot holes at the three locations on the mounting template.
5. Use screws or bolts to secure the mounting portion of the CCU bracket.
To secure the CCU in the CCU bracket:
1. Connect the CCU cable and the NMEA 2000 drop cable to the CCU.
2. Place the CCU in the mounting portion of the CCU bracket with the wires hanging straight down, toward
the water.
3. Place the securing portion of the bracket over the ball and snap it into the mounting portion of the bracket,
starting with the two arms that do not have the thumbscrew.
4. Make sure the cables hang straight down, toward the water, and connect the arm with the thumbscrew.
The cables must hang straight down for the CCU to accurately read your heading.
5. Hand-tighten the thumbscrew until the CCU is held firmly in the bracket. Do not overtighten the
thumbscrew.
