CCU Mounting and Connection Considerations

• The CCU is the primary sensor of the Compact Reactor 40 Hydraulic autopilot system. For best performance,

observe these considerations when selecting a mounting location.

◦ A handheld compass should be used to test for magnetic interference in the area where the CCU is to be

mounted(Testing a Location for Magnetic Interference,

◦ The CCU should be mounted on a rigid surface for best performance.

• Mounting screws are provided with the CCU. If you use mounting hardware other than the provided screws,

the hardware must be quality stainless or brass material to avoid magnetic interference with the CCU.

Test any mounting hardware with a handheld compass to make sure no magnetic fields are present in the

hardware.

• The CCU cable connects the CCU to the ECU and is 5 m (16 ft.) long.

◦ If the CCU cannot be mounted within 5 m (16 ft.) of the ECU, extension cables are available from your local

Garmin dealer or at garmin.com.

◦ This cable must not be cut.

Finding the Best Mounting Location

1 Create a list of all suitable mounting locations for the CCU.

Suitable mounting locations should not be within 60 cm (2 ft.) of the following:

• Iron

• Magnets

• High-current wires

• Intermittently-running pumps, such as head pumps and live well pumps

A large magnet, such as a subwoofer-speaker magnet, should be no closer than 1.5 m (5 ft.) to any of the

mounting locations.

2 Locate the center of rotation of the boat, and measure the distance between the center of rotation and each

of the suitable mounting locations you listed in step 1.

3 Select the location closest to the center of rotation.

If more than one location is approximately the same distance from the center of rotation, you should select

the location that best meets these considerations.

• The best location is closest to the centerline of the boat.

• The best location is lower in the boat.

• The best location is slightly forward in the boat.

Testing a Location for Magnetic Interference

You can use a handheld compass to test a mounting location for magnetic interference.

1 Hold a handheld compass in the CCU mounting location.

2 Move the compass six inches to the left of the location, then six inches to the right, observe the needle, and

select an action:

• If the compass needle moves more than three degrees during this step, magnetic interference is present.

Select a new mounting location and repeat the test.

• If the compass needle does not move, or moves less than three degrees, proceed to the next step.

3 Repeat this process while moving the compass above and below the mounting location.

4 Repeat this process while moving the compass in front of and behind the mounting location.
