1.4 Connecting the Power and the Drive unit
CAUTION:
Use of incorrect power cable size could cause your SmartPilot to
malfunction and will reduce the power supplied to the drive unit.
Ensure the correct size is used and if in doubt, use a heavier gauge
cable.
Note:
For Volvo Penta IPS autopilot systems a motor connection is not required. For more
information, please refer to the Connections guide supplied with the DPU.
To connect the power and motor connections, follow the steps below:
1. Measure the total length of cable run from the boat’s distribution panel to the
SmartPilot computer.
2. Select the appropriate size cable (distribution panel to SmartPilot computer):
Note:
* These specifications apply to the cabling for CR
solenoids
. Power the CR pump
motor
separately, as specified in the CR pump installation guide.
