Garmin GSR 56 Installation Manual - Page 15

2 INSTALLATION 2.1 Introduction This section provides hardware equipment information for installing the GSR 56 and related hardware. Installation of the GSR 56 should follow the aircraft TC or STC requirements. Cabling is fabricated by the installing agency to fit each particular aircraft. The guidance of FAA advisory circulars AC 43.13-1B and AC 43.13-2A, where applicable, may be found useful for making retro-fit installations that comply with FAA regulations. Refer to the G1000 System Installation Manual, Garmin part number 190-00303-00 for further details on the mechanical aspects. 2.2 Installation Materials The GSR 56 is available as a single unit under the part numbers listed in Table 2-1. Table 2-1.

The standard pin contacts supplied in the connector kit are compatible with 22, 24, 26, & 28 AWG wire. In cases where some installations have more than one unit sharing a common circuit breaker, sizing and wire gauge is based on aircraft circuit breaker layout, length of wiring, current draw of units, and internal unit protection characteristics. Do not attempt to combine more than one unit on the same circuit breaker unless it is specified on aircraft manufacturer approved drawings. In some cases, a larger gauge wire such as 16 or 18 AWG may be needed for power connections. 16 & 18 AWG compatible pins are provided in the connector kit for these power and ground connections. Special thin-wall heat shrink tubing is also provided to insulate the extended barrels inside the backshell. If using #16 or #18 barrel contacts, ensure that no two contacts are mounted directly adjacent to each other. This minimizes the risk of contacts touching and shorting to adjacent pins and to ground. Ensure that routing of the wiring does not come in contact with sources of heat or RF/EMI interference. Check that there is ample space for the cabling and mating connectors. Avoid sharp bends in cabling and routing near aircraft control cables. GSR 56 Installation Manual 190-00836-00 Page 2-1 Revision F
