02 INSTALLING THE PRODUCT
Connecting the power terminal
Connect the cables to the terminal board with solderless ring terminals.
Properly connect the cables by using certied and rated cables and make sure to x 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, re can occur due to arc heat
generation and if the terminal is too tight, terminal board could get damaged.
