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.
