Chapter 3: System Installation NOTE: A ground strap from the end-effector to the base mounting pad must include a service loop that allows full rotation and movement of the tool flange. Grounding Robot Base to Frame NOTE: You must ground the robot to the frame for all installations. l Use any of the three M12 mounting screws for this connection. Screws must be stainless or zinc-plated steel. l Use an external-tooth star washer, touching the mounting screw head. Washers must be stainless or zinc-plated steel.
If the frame is painted where the M12 screw makes contact with it, use a ring terminal under the star washer, and connect the other end of the wire from the terminal to a suitable grounding surface on the frame. If the frame is not painted where the M12 screw makes contact with it, you do not need to use a ring terminal, just put an external-tooth star washer under the mounting screw head. If frame is painted under screw head. Use ring terminal and run the other end to an unpainted part of the frame. M12 Screw External-tooth star washer If frame is unpainted under screw head. Use star washer, but not ring terminal.
