CHAPTER 3 Installation
3 Protective Bonding
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 pro-
tective conductor. (See Fig. 3-7)
(Symbol 417-IEC-5019)
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 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
marking, follow the instructions on protective bonding explained in the
"OMRON Robot Controller User's Manual".
4) Use a ground cable with a conductor wire cross section of at least 2.0mm
2
and a length within 1 meter.
WARNING
BE SURE TO GROUND THE ROBOT AND CONTROLLER TO PREVENT
ELECTRICAL SHOCK.
WARNING
TURN OFF THE CONTROLLER BEFORE GROUNDING THE ROBOT.
