TM 1-6625-724-13&P0070 000070 00-7Figure 3. Magnetic RPM Sensor Installationk. Tie-wrap the magnetic RPM sensor cable to existing hydraulic tubes and supports with enough slack to allowfull swashplate movement.CAUTIONBe sure that magnetic RPM sensor cable cannotinterfere with any moving components, as thisinstallation is used during flight. When routingcable, make sure that there is enough slack so thatwhen the swashplate moves it will not damagecable.I. Route the cable out of the swashplate access door. Secure it with enough slack to allow for fully extended leftfront control rod, but not enough for the cable to become entangled with any moving components. The cablemay be routed through the hydraulic compartment and into the back of the cockpit.m. Connect magnetic RPM sensor cable to the DAU receptacle marked TACHO 1.PROCEDURE 3: ACCELEROMETER INSTALLATIONNOTEThe lateral accelerometer must be mounted to thebulkhead, not to a shock-mounted component.LATERAL ACCELEROMETERa. Install lateral accelerometer (28110900) on accelerometer mounting bracket (29313000), then connectaccelerometer cable (29105605) to lateral accelerometer. Mount accelerometer bracket (29313000) to thepilot's compartment aft bulkhead (rear canopy bulkhead), with the connector pointing to the right of thehelicopter (to your left when you are facing the bulkhead), see figure 4.b. Connect accelerometer cable (29105605) from lateral accelerometer to the DAU receptacle marked ACC1.
