When terminating a frame ground, use the Kepnut provided with the ONS 15454 and tighten it
to a torque specification of 31 in-lb (0.36 m-kg). The Kepnut provides a frame ground
connection that minimizes the possibility of loosening caused by rotation during installation and
maintenance activity. The type of prevention the Kepnut provides for the frame ground
connection is inherently provided by the terminal block for battery and battery return
connections.
