  • Page 61 5.6.2.2 Installation Harness routing It is important to route all CAN1 harnesses in a way that protects them from standing water, physical damage, from being stepped on, or from being pulled. Best practice is to run the harness through PVC conduit. Use tie wraps or other means to secure harnesses at all connection points, at entry and exit from rigging conduit, and at regular intervals along its length if you do not have rigging conduit.

  • Page 62: Can2 Connection

    CAN2 connection The CAN2 network is used to connect the CANtrak display and a third- party autopilot that is certified by Dometic to work with the EPS system. The CAN2 network is optional on single-engine systems; if you are not using an autopilot, leave the cap on the harness connector, coil the harness, and secure it out of the way.
  • Page 63 5.6.3.1 Planning You will need to build a small CANbus network with a node (tee connector) for each actuator, each display, and for the autopilot. Locate the nodes close to the devices and use an extension harness to create a network backbone. Your network will look similar to figure 5-22 (only one actuator is shown, but you will need to connect both in a multi-engine system).
