3.6 Grounding the robot system
General instructions on grounding the robot system
Three ways of grounding are shown in Fig. 3-24.
●
Separate grounding is the best solution.
– The robot arm is grounded at an M4 threaded hole (see Tab. 3-8) on the base area.
– The controller is grounded together with the mains line (feed) connection.
To ground the controller, proceed as described in Section 4.2.
●
If possible, the grounding of the robot arm must be separated from other units/devices.
●
The minimum cross-section of the grounding cable must be 4,2 mm².
●
The grounding cable is not included in the scope of delivery of the robot system.
●
The grounding cable should be kept as short as possible.
