Sometimes, the CAN_GND voltage level of different CAN devices on a CAN bus

system are not equal. In this case, it could cause some problems and derogate the

system stability. There is one way to relieve this situation; users can connect the

CAN_GND of different CAN devices with each other to balance the voltage level of

CAN_GND.

Electronic circuits are always influenced by different levels of Electro-Static

Discharge (ESD), which become worse in a continental climate area. F.G. provides a

path for conducting the ESD to the earth ground. Therefore, connecting the F.G

correctly can enhance the capability of the ESD protection and improve the module's

reliability.

Wiring of CAN_GND and F.G. is not necessary; users can modify the configuration

of wiring according to real applications.
