Electrical safety Make sure you have switched off the power supply before you start installing this product Follow these steps to install your linear drive unit 1 Consult the EMC installation guidelines page 6 2 Mount the drive page 8 3 Connect to the course computer page 12 4 Complete the check page 14 1 EMC installation guidelines All Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine environment Their design and manufacture conforms to the appropriate Compatibility EMC standards but correct installation is required to ensure that performance is not compromised Although every effort has been taken to ensure that they will perform under all conditions it is important to understand what factors could affect the operation of the product The guidelines given here describe the conditions for optimum EMC performance but it is recognized that it may not be possible to meet all of these conditions in all situations To ensure the best possible conditions for EMC performance within the constraints imposed by any location always ensure the maximum separation possible between different items of electrical equipment For optimum EMC performance it is recommended that wherever possible Raymarine equipment and cables connected to it areLinear Drive Installation Guide 7 At least 3 ft 1 m from any equipment transmitting or cables carrying radio signals eg VHF radios cables and antennas In the case of SSB radios the distance should be increased to 7 ft 2 m More than 7 ft 2 m from the path of a radar beam A radar beam can normally be assumed to spread 20 degrees above and below the radiating element The equipment is supplied from a separate battery from that used for engine start Voltage drops below 10 V and starter motor transients can cause the equipment to reset This will not damage the equipment but may cause the loss of some information and may change the operating mode Raymarine specified cables are used Cutting and rejoining these cables can compromise EMC performance and must be avoided unless doing so is detailed in the installation manual If a suppression ferrite is attached to a cable this ferrite should not be removed If the ferrite needs to be removed during installation it must be reassembled in the same position Suppression ferrites The following illustration shows typical cable suppression ferrites used with Raymarine equipment Always use the ferrites supplied by Raymarine This product has ferrites mounted internally D35482 Figure 3 Typical suppression ferrites Connections to other equipment If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine a suppression ferrite MUST always be attached to the cable near to the Raymarine unit8 Linear Drive Installation Guide 2 Mounting the drive Mounting the drive unit involves four main steps ensuring correct drive alignment securing the drive to the boat connecting the drive to the steering system completing a steering check Drive alignment When mounting the linear drive unit check that it is aligned correctly The main drive assembly must be at right angles to the mounting surface see Figure 4 The drive unit must be at right angles to the tiller arm when the rudder is amidships see Figure 4 A mid stroke Side view 90 Drive A mid stroke B tiller arm radius

be accurately aligned with the tiller arm plane of rotation The ball end fitting only allows up to 5 degrees misalignment between the push rod and tiller arm plane of rotation see Figure 5 CAUTION Accurate angular alignment is extremely important You must not exceed this 5 degree limit under any Drive Installation Guide 9 5 Max 5 Max D50781 Figure 5 Alignment between push rod and tiller arm plane of rotation Securing the drive Mounting location Before you secure the drive to your boat you must first check the suitability of the mounting location CAUTION Consult the boat manufacturer if you have any doubt about the strength or suitability of the mounting location Structural strength This drive produces a considerable amount of force so you must mount it on a solid structure ie a substantial frame member in the boat In some cases you may need to build a special frame to mount the drive unit To prevent excess noise and vibration do not attach this drive to any structures that support cabins Drive orientation You can attach the drive unit mounting foot to any suitable horizontal or vertical surface If required you can also mount the drive unit upside down General position Refer to the EMC installation guidelines page 6 Make sure the drive will be accessible for future servicing Environment This drive is not waterproof so you should mount it in a dry location clear of any bilge water10 Linear Drive Installation Guide Securing bolts Attach the mounting foot with four stainless steel M10 38 inch bolts and lock nutslock washers Note Always mount the drive as securely as possible to make sure it performs reliably and remains correctly aligned Connecting to the steering system CAUTION Consult the steering gear manufacturer if you have any doubt about the strength of the existing tiller arm or rudder quadrant This drive produces a considerable amount of force so you must ensure that your tiller arm or rudder quadrant can cope with the peak thrust specified in the Table 1 Drive specifications Use one of these methods to attach the push rod to the rudder stock 1 Independent tiller arm we recommend that you attach the linear drive unit to the rudder stock via an independent tiller arm the Edson and Whitlock companies offer standard fittings for their steering systems 2 Steering linkage tiller arm or rudder quadrant in certain cases you may be able to attach the push rod to the same tiller arm or rudder quadrant used by the main steering linkage Consult the steering manufacturer before you modify the rudder quadrant Attaching the rod end Use the supplied tiller pin assembly to attach the rod end to the tiller arm at the tiller arm radius shown in Figure 4 1 Attach the tiller pin to the tiller arm insert the tiller pin through the tiller arm hole so the flange remains above the arm see Figure 6 make sure that the tiller pin is a tight fit in the tiller arm use the supplied lock washer and fully tighten the lock nut Note If necessary you will need to drill a 13 mm 052 in hole in the tiller arm at the radius shown in Figure 4 2 Attach the rod end to the tiller pin place the rod end onto the tiller pin secure with the supplied washer and Rclip see Figure 6Linear Drive Installation Guide 11 Rclip Washer Rod end Flange Tiller arm Lock Lock nut washer Tiller pin Hole diameter 13 mm 052 in D50761 Figure 6 Attaching the push rod to the tiller arm Steering check When you have mounted the drive unit turn the boats steering wheel from hardover to hardover and check that Angular movement of the ball end fitting is less than 5 degrees see Figure 5 If you exceed this 5 degree limit the drive will catch on the tiller armrudder quadrant and the ball joint will bind No part of the drive unit fouls the boats structure when the push rod moves in and out The total rudder movement is limited to 35 degrees by the steering system end stops rather than the linear drives end limits see Figure 7 Steering system Steering system end stop end stop 35 35 D50791 Figure 7 Total rudder movement CAUTION Make sure rudder movement is limited by the steering system end stops before the push rod reaches its end stop Failure to do this could damage the drive and will invalidate the warranty12 Linear Drive Installation Guide WARNING Keep clear of moving steering systems at all times Protect moving parts from access during normal use 3 Connecting to the course computer WARNING Electrical safety Make sure the power supply is switched off before you make any electrical connections The linear drive unit has electrical connections for the drive motor two singlecore cables red and black the clutch a twocore cable with red and blue cores Follow these steps to connect the linear drive to the course computer 1 Measure the distance of cable run
