    1.2 INSTALLATION PREPARATION This section provides electrical and mechanical information needed for planning the physical layout of the G5 installation. Use the information in Section 1.2 to become familiar with all aspects of the installation before actually beginning the physical installation of any equipment into the aircraft.

  • Page 18: Wiring/Cabling Considerations

    Installation Manual 1.2.1.1 POWER SPECIFICATIONS The G5 is capable of operating at either 14 or 28 VDC. Table 1-3 lists the supply voltage and current draw information for the G5. Use this information when determining power supply requirements. All installed electrical appliances must be considered when determining total power requirements.
  • Page 19 Contacts for the connectors must be crimped onto the individual wires of the aircraft wiring harness. Table 1-2 lists contact part numbers (for reference) and recommended crimp tools. CAUTION: Check wiring connections for errors before connecting any wiring harnesses. Incorrect wiring could cause internal component damage. 190-02072-00 Rev. B Garmin G5 User's Manual...
  • Page 20 There is no minimum node length. The G5 installation kit provides a DB-9 CAN Bus terminator that contains a 120 Ohm resistor connected between pins 1 and 2 (Figure 1-2). The GSA 28 servos contain a 120 Ohm resistor inside the unit that provides the termination when pin 3 is connected (outside of the unit) to pin 4 (Figure 1-3).
  • Page 21 LRUs together into a single connection point. 2) Keep all node lengths as short as practical. 3) If a G5 or GAD 29 (that was used as a CAN bus termination) is removed, the CAN bus will remain terminated as long as the CAN bus terminator (Figure 1-2) is left connected.

    Installation Manual 1.3.3.2 ADDITIONAL EQUIPMENT REQUIRED A 3/32” hex drive tool is required to secure the G5 to the panel as described in Section 1.3.6.3 and shown in Figure 1-7. Air hoses and fittings are required to connect pitot air and static air to the G5. The G5 uses a female 1/8-27 ANPT fitting for each of these ports.
  • Page 27 G5. The G5 should be rigidly mounted to the aircraft panel. • The G5 must be leveled to within 30.0° of the flight level cruise attitude. An air- craft leveling and offset calibration procedure must additionally be carried out prior to flight.
  • Page 28 1/8-27 ANPT male threads. NOTE: The temporary port plugs attached to the pressure ports on a new G5 are not suitable for flight and must be removed prior to the installation of G5 into the aircraft.
  • Page 29 Avoid sharp bends in the tubing and attempt to route hoses away from aircraft control cables. The G5 should not be at the low point of the pneumatic plumbing lines to avoid moisture or debris collecting at or near the unit. Ensure that no deformations of the airframe surface have been made that would affect the relationship between static air pressure and true ambient static air pressure for any flight condition.

  • Page 30: Antennas

    NOTE: Use of different colored tubing is recommended for static and pitot plumbing to avoid plumbing connection errors. Incorrect plumbing connections will result in erroneous air data information calculated by the G5. Observe the following cautions when connecting pneumatic lines:...
