WARNING
Be sure to ground the robot and controller to prevent electrical
shock.
WARNING
Turn off the controller before grounding the robot.
The robot must be grounded as follows:
1) Provide a terminal marked “PE” for the protective conductor of the entire
system and connect it to an external protective conductor. In addition, se-
curely connect the ground terminal on the robot to the same protective con-
ductor.
(Symbol 417-IEC-5019)
2) The Z-axis ground terminal can also be used when the end effector uses an
electrical device which, if it malfunctions, might make contact with the power
supply. To check the ground terminal locations, refer to Chapter 6, “Specifi-
cations”.
3) For details on protective bonding on the robot body to comply with CE mark-
ings, follow the instructions on protective bonding explained in the YAMAHA
Robot Controller Owner's Manual.
! CAUTION
• Use a ground cable thicker than the AWG14 (2.0mm
