When terminating battery and battery return connections as shown in
follow a torque specification of 10 in-lbs. When terminating a frame ground, use the kep-nut
provided with the ONS 15454 and tighten it to a torque specification of 31 in-lbs. The kep-nut
provides a frame ground connection that minimizes the possibility of loosening caused by
rotation during installation and maintenance activity. This type of prevention is inherently
provided by the terminal block for battery and battery return connections.
Do not secure multiple connectors with the same bolt assembly.
