1.1.2.1 Protective Earth and Functional Earth
Protective Earth (PE) and the Ground (GND) of the electronic boards are electrically isolated.
The blank bottom side of the heatsink has a flat conductive surface and can be used as a connection
for Protective Earth (PE) or Functional Earth (FE).
To fulfill the PE requirements and also have a better EMI shielding around the electronic boards, it is
necessary to electrically connect the conductive surfaces (marked yellow and green in the following
picture) to the chassis of the motor or the robot.
Note
