Requirements:
• The potential equalization must be connected to the external ground terminal on the
device.
• For optimum electromagnetic compatibility, keep the potential equalization line as short
as possible.
• The recommended cable cross-section is 2.5 mm
• The potential equalization of the FDR56/FQR56 must be included in the local potential
equalization.
