 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

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
