  1. Attach the ring lug to the wire.
    Note NI recommends using a right angle ring lug to ensure sufficient cabling clearance for the ground wire. If your system uses a single module, a standard ring lug may be sufficient for cabling clearance.
  2. Remove the grounding screw from the grounding terminal on the bottom of the module.
  3. Fasten the ring lug to the grounding terminal.
  4. Tighten the grounding screw to 0.5 N · m (4.4 lb · in.) of torque.
  5. Attach the other end of the wire to the chassis safety ground using a method that is appropriate for your application.
