In case you are running several servo drives behind a contactor, please use an uni-directional TVS diode on
each drive because of the inductances of the wiring.
1.2.3.1.1.1.1.1 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.
Important
Please ensure that the chassis is properly grounded.
