Tightening power terminal
Connect the cables to the terminal board using the compressed ring terminal.
Use rated cables only.
Connect the cables with driver and wrench that can apply the rated torque to the screws.
Make sure that appropriate tightening torque is applied for cable connection. If the terminal is loose, arc heat may occur
and cause fire and if the terminal is connected too firmly, terminal may get damaged.
