3.6 Grounding the robot system
General instructions on grounding the robot system
Three ways of grounding are shown in Fig. 3-23.
●
Separate grounding is the best solution.
– The robot arm is grounded at an M4 threaded hole (see Fig. 3-24) on the base area.
– The control unit is grounded together with the mains line (feed) connection.
To ground the control unit, 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 2.0 mm² (RV-2SD/RV-2SQ) or 3.5 mm²
(all other models)
●
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.
