5.7 ESD Features

Pay great attention to ESD protection when using the MG323 module. To ensure that the working reference GND is connected to the MG323 module and user interface board properly, you are recommended not to spray a coated insulation on the structure fixing hole (connecting with the main reference GND of the user interface board) and connect the hole with the MG323 module through the metal fastener or other low-resistance fastener. For specific installation method and fastener specification, see “6.4 MG323 Module Installation Description."
