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.
Caution
• When removing the outer sheath of the power supply cable, be careful not to scratch the inner sheath of the
cable.
• Make sure that more than 20mm of the outer sheath of the indoor unit power and communication cable are
inside the electrical component box.
• Install the communication cable separately from power cable and other communication cables.

Selecting solderless ring terminal
Select a solderless ring terminal for a power cable according to the nominal dimensions for cable.
Apply insulation coating to the connection part of the solderless ring terminal and the power cable.
