Reduced electrical noise
Proper shielding
Reliable operation in large installations
Grounding should always be connected to the system ground or chassis ground when available.
Most controllers can be grounded using:
The mounting holes located on the controller PCB
The dedicated grounding connector (if present)
These grounding points are normally located near the corners of the controller board.
For Skin Mesh controllers:
⚠ Only the two mounting holes on the connector side can be used as grounding points.
