Each crystal frame must be grounded for EMC reasons and to ensure the correct operation of the physical controls.

If the frame is not properly grounded, then you may see some odd behaviours once the console is operational. For example, the faders do not move as expected.

Grounding Instructions

A grounding screw is provided on the connector panel (at the rear of the frame).

To ground the frame, please read and observe all of the instructions in the "General Safety Information for Lawo Equipment" booklet delivered with your devices.


(E) CAUTION

Each frame must be on the same potential as all other system devices.

ALWAYS use a grounded mains connection, to prevent the device from being grounded through Ethernet or other signal connections.

The device must be connected to an additional fixed protective ground if it is conductively connected with more than 20 other devices. i.e. more than 20 copper I/O connections. For more information, please refer to the "General Safety Information for Lawo Equipment" booklet delivered with your devices.

Use the M4 x 10mm screw to fasten the grounding cable to the housing. You should use a Torx T20 driver for this purpose.

If the surface includes more than one frame, then it is important to ground each frame.
