10.3.4 Connection Tightening Torques
When tightening all electrical connections, it is very
important to tighten with the correct torque. Too low or
too high torque results in a bad electrical connection. Use
a torque wrench to ensure correct torque. Always use a
torque wrench to tighten the bolts.
