3. A successful installation should start with careful planning including determination of mounting location for the SL70 antenna location and mounting connections to an altitude data source power cable routing and other required modifications Once the mounting location has been determined prepare the mounting frame for installation It may be easier to complete the wiring harness and attach the connectors to the mounting frame prior to installing the mounting frame in the aircraft INSTALLATION CONSIDERATIONS MOUNTING CONSIDERATIONS The SL70 is designed to mount in the avionics stack in the aircraft instrument panel within easy view and reach of the pilot The standard package includes the mounting frame for ease of mounting connections and service of the unit Allow an additional one inch clearance to the rear of the mounting frame for connections and cables For typical installations the SL70 does not require external cooling When mounting the unit leave a clearance of 1 8 to 1 4 inch between avionics to allow for air circulation MINIMUM SYSTEM CONFIGURATION The SL70 requires connections to the following equipment as a minimum e power input e altitude data gray code or RS232 e astandard transponder antenna ALTITUDE INPUT The SL70 can use either a standard altitude gray code input from an encoding altimeter or an RS 232 input from a serial encoder For new installations a serial encoder is recommended because it simpli
