Page 7: Actuator Installation
Electric Inboard Steering Actuator Actuator installation CAUTION! This actuator is intended to operate in a primarily dry area that may be wet or occasionally submerged. It is not intended to operate in a permanently submerged condition. NOTICE! Protect the actuator shaft from nicks and scratches during installation. A damaged shaft cannot be repaired. - Page 8 If space and geometry allows, mount the actuator as shown for EA30xx. In wakeboat applications, space constraints may prevent mounting the actuator as directed. Such cases cannot be adequately covered in this manual — please contact Dometic for assistance. Table 1.

Leave the protective cover on the harness connector until you are ready to connect it to the actuator, otherwise the connector may be damaged. The harness is supplied with a bulkhead plate and cord grip pre-installed. You may not need this bulkhead fitting, in which case we recommend that you use a tie wrap on one of the mounting holes to secure the plate to a fixed point on the boat.

- Page 21 Electric Inboard Steering Actuator 5.2.2 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 22 CM21504 HARNESS 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. NOTE The details of each autopilot’s network connection will be specific to the manufacturer, so be sure you read and understand the instructions that come with the autopilot system.

- Page 26 Electric Inboard Steering Actuator Ignition sensing The Electric Actuator harness has a single purple ignition-sensing wire that must be connected to an ignition source (has system voltage when ignition is on). This wire provides the wake-up signal to the Electric Actuator; the steering system will not work without it.

Page 29: Setup And Configuration
Electric Inboard Steering Actuator Setup and configuration Before the Optimus EPS system can be used it must be configured. At a minimum, you need to do the Initial Setup and the Steering Setup. In the Initial Setup you will specify the type of system you are configuring, as well as the number and location of the devices that are installed. - Page 30 Electric Inboard Steering Actuator 6.2.3 Select number of devices The CANtrak will display a list of devices based on the system type. Use the + and – buttons to change the quantity of each device to match the system. These parameters tell the system how many of each device to look for on the CAN network.
- Page 31 Electric Inboard Steering Actuator Steering setup The setup steps in this section are required for all Optimus EPS systems. All the steering setup tasks are done from the Steering Setup menu at Dealer Menu > Initial Setup > Steering. 6.3.1 Configuration The configuration step teaches the SCU about your steering geometry.
- Page 32 Electric Inboard Steering Actuator If the calibration fails, the screen will display a warning symbol and display “Calibration failed” in the status field. Double check the installation and ensure that there is no interference that is preventing the steering actuator(s) from moving through their full stroke.
- Page 33 Electric Inboard Steering Actuator NOTE • Sometimes the boat will not track straight through the water when the rudder is aligned straight ahead. You can correct this by performing the straight line correction again during a sea trial. Steer the helm until the boat is tracking straight at cruising speed, then press Set.
