Electrical Wiring

2. Cut the power cable to an appropriate length and connect it to terminals L and N in the power

supply box with a solderless ring terminal (see Figure 17).

3. If two cables are connected to one terminal, place the cables back to back with the thin cable

upward and the thick cable downward, as shown in the detail in Figure 17.

4. Secure the cable(s) with a cable tie and provide strain relief.

5. Replace the cover on the terminal board.

Note: Make sure that the section of the power supply cable that has the sheath removed is

inside the power supply box. If this is not possible, connect the power cable conduit to

the power supply box.

6. Pull the power cable through the designated knock-out at the bottom right of the mini outdoor

unit (refer to Figure 15, p. 23/Figure 16, p. 24).
