2.2 Ground
connections
In the galvanically isolated version, the GND of CAN1 (X3) and CAN2 (X4) is iso-
lated in each case from the rest of the circuit, the GND of the serial interface (X2)
is connected to the GND of the power supply (X1).
In the version without galvanic isolation, all GND connections (X1, X2, X3, X4)
are connected with each other.
The shield connections of CAN1 (X3), CAN2 (X4), serial interface (X2) and power
supply (X1) are connected with each other both in the version with and in the
version without galvanic isolation.
