10. Installation
Connecting the power terminal
▶ Connect the cables to the terminal board with solderless ring terminals.
▶ 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 complying rated torque value. If the terminal is loose, fire can occur due to arc
heat generation and if the terminal is too tight, terminal board could get damaged.
