Step 3: Install the Course Computer 15Step 33.4 Attach the power cablesWARNING: Electrical safetyMake sure the power supply is switched off before you make anyelectrical connections.Follow these steps to provide power to the course computer:1. Measure the total length of cable run from the boat’s distributionpanel to the course computer, then use Table 3-1 to identify theappropriate cable size.Note: When selecting power cable you must use the gauge specifiedin Table 3-1. If in doubt, use a heavier gauge cable than specified.A lighter gauge cable might cause a voltage drop between the supplyand the course computer. This could cause the course computer tomalfunction and will reduce the power supplied to the drive unit.2. Route the cables back to the course computer, taking into accountthe EMC installation guidelines (page 7).3. Install a circuit breaker or fuse on the power supply to suit thedrive unit connected to your autopilot system (see Table 3-2).4. Connect the cables to the POWER inputs on the course computer.5. Attach the suppression ferrite (supplied) around both the positiveand negative power cables, between the cable clamp and coursecomputer.
