2.2.5 Grounding procedures
(1) Grounding methods
, there are three ways of grounding (earthing) the RV-5AS. The most preferable
of the three is "a". Do not use "c". For information on grounding (earthing) the robot controller, refer to
the separate Instruction Manual "Controller Setup and Maintenance".
2) Use Class D grounding (grounding resistance 100
Ω
or less). Dedicated grounding separated from the
other devices should be used.
3) Use a AWG#11(4.2mm
2
) or more stranded wire for the grounding wire. The grounding point should be
as close to the robot arm and controller as possible, and the length of the grounding wire should be
short.

(2) Grounding procedures
1) Prepare the grounding cable (AWG#11(4.2mm
2
) 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.
