2.5 Shield Block Grounds
The connectors on Garmin G1000 LRUs utilize the Shield Block grounding system to provide necessary
ground reference to wire shielding and/or transducers. The shield block termination method allows multiple
grounds to be terminated directly to a block mounted to the connector backshell assembly. Shielding and
grounding requirements for all other LRUs and connectors are shown in the respective install drawings.
