Chapter 2: Installing the system 21
At the Course Computer, locate the free ends of the cables from the distribution panel
and Drive. Ensuring all power is switched off, refer to the illustration above and
connect each cable to the correct Course Computer terminals as follows:
1. Strip 8-10 mm (3/4 inch) of insulation from the end of each wire.
2. Use a small screwdriver to loosen the relevant screws on the terminal block.
3. Insert the stripped wires into the appropriate terminals then tighten the terminal
block screws.
2.6 Fluxgate Compass
Note: If you intend using a separate NMEA compass, do not connect the Fluxgate Compass
supplied with your SPX-5R Drive system. Instead, connect the NMEA compass to the NMEA in-
put on the SPX-5R system.
Use these instructions to install the Fluxgate Compass. After fitting the Fluxgate
Compass, ensure you affix the compass safe area label adjacent to the Fluxgate
Compass.
The compass contains a self-levelling mechanism. This enables the compass to
provide accurate readings with pitch and roll movements up to +/- 35°.
Note: When shaken, the Fluxgate Compass makes a rattling sound. This is entirely normal and
is not a cause for concern.
Compass mounting
Location
To achieve the best performance, mount your compass:
• With the Raymarine logo facing the bow.
• As close as possible to the boat’s pitch and roll center.
• At least 2ft 6 in (0.8 m) away from your boat’s steering compass to avoid deviation
of both compasses.
• As far away as possible from other cables and large iron masses, such as the
engine or other magnetic devices.
Note: To check if the intended mounting location is free from magnetic influence, tape a hand-
held compass to the chosen location, then turn the boat through 360°. The readings on the hand-
held compass and your boat’s main steering compass (if accurately aligned) should not differ by
more than10° at any heading.
