6.8.1 Grounding
Although operator protection is guaranteed, it is best to establish an additional ground for EMC reasons. A
grounding screw is provided below the DC IN connector on the rear of the frame.
1. Using a M4x8 screw, fasten the grounding cable to the CASE bolt.
2. If installing Power Core with a control surface, then establish a direct connection to the control surface
modules using the CAN bus.
Power Core must be on the same potential as all other system devices.
For Scandinavian countries, ALWAYS use a grounded mains connection, to prevent the device from being
grounded through Ethernet or other signal connections.
Grounding of Audio Interfaces
For compliance with AES3, digital interfaces should be connected to a field ground.
For microphones, the ground from the device should connect directly to the microphone via the cable shielding,
otherwise phantom power cannot be transferred. Take care that the shielding does not connect to the field
ground, to prevent interference and loss of signal quality.
