4.5 Grounding the Robot System
4.5 Grounding the Robot System
Proper grounding is essential for safe and reliable robot operation. Follow these recom-
mendations to properly ground your robot.
IMPORTANT:
The resistance of the ground conductor must be ≤ 10 Ω.
WARNING:
ELECTROCUTION RISK
Failing to ground robot-mounted equipment or tooling that uses hazardous
voltages could lead to injury or death of a person touching the end-effector
when an electrical fault condition exists.
If hazardous voltages are present at any user-supplied robot-mounted equipment or tooling,
you must install a ground connection for that equipment or tooling. Hazardous voltages can
be considered anything in excess of 30 VAC (42.4 VAC peak) or 60 VDC.
If there will be hazardous voltages present at the tool flange or end-effector, you must:
l
Connect the mounting frame to protective earth ground.
l
Ground the robot base to the mounting frame.
The iCS-ECAT is grounded to the robot base through a conductive gasket.
l
Ground the end-effector to the robot base.
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
with 4 axis robots.
Grounding the Robot Base
The robot base must be properly grounded to the mounting frame.
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 ground-
ing 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. Use an external-tooth star washer under the mounting screw head.
