. Installation
Connecting the power terminal
•
Connect the cables to the terminal board using a solderless ring terminal.
•
Properly connect the cables by using certified and rated cables and make sure to fix them properly so that external force
is not applied to the terminal.
•
Use a driver and wrench that can apply the rated torque when tightening the screws on the terminal board.
•
Tighten the terminal screws by applying rated torque value. If the terminal is loose, arc heat may occur and cause fire and
if the terminal is connected too firmly, terminal may get damaged.
Connect one cable per
terminal and fix it with a
solderless terminal .
