Fig.2-4 : Grounding methods
1)There are three grounding methods as shown in Fig.
2)Use Class D grounding (grounding resistance 100Ω or less).
Dedicated grounding separated from the other devices should be used.
3)Use a AWG#11(3.5mm2) or more stranded wire for the grounding wire. The grounding point should be as close to the robot arm and controller as possi- ble, and the length of the grounding wire should be short.

1)Prepare the grounding cable (AWG#11(3.5mm2) or more) and robot side installation screw and washer.
2)If there is rust or paint on the grounding screw section (A), remove it with a file, etc.
3)Connect the grounding cable to the grounding screw section.
CAUTION When installing the robot, be sure to allocate a sufficient maintenance space for connecting the cables between devices and replacing a backup battery at the rear of the robot.
