CAUTION
• A secure ground connection (less than 100-ohm resistance to ground) is recom-
mended.
• Use electrical wire thicker than AWG14 (2mm 2 ) as the ground wire.
WARNING
Always turn off the power to the controller before making the ground connection.
Provide a terminal marked “PE” as the protective conductor for the entire system, and connect it
to an external protective conductor. Also securely connect the ground terminal on the robot frame
to the protective conductor.
