Be sure to ground the robot and controller to prevent electrical shock.

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 pedestal to the same protec-
tive conductor. (See Fig. 3-6.)

2) When the end effector uses an electrical device which, if it malfunctions,

might make contact with the power supply, the user must provide proper
grounding on his own responsibility. The YK-X series robots do not have a
ground terminal for this purpose.

3) For details on protective bonding on the robot body to comply with CE mark-

ing, follow the instructions on protective bonding explained in the "YAMAHA
robot controller owner's manual" or "CE marking manual".

4) Use a ground cable with a conductor wire cross section of at least 2.0mm

and a length within 1 meter.
