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.
