Work procedure
1. R emove 2 screws to detach the electric component cover.
2. R oute each cable through the wiring intake into the electric component box. (Procure
power supply cable and indoor/outdoor connecting cable locally.)
3. S ecurely connect the power supply cable and the indoor/outdoor connecting cable
to the terminal blocks.
4. S ecure the cables with clamps outside the electric component box.
5. A ttach the electric component cover as it was.
• Fix power supply cable and indoor/outdoor connecting cable to electric component
box by using buffer bushing for tensile force. (PG connection or the like.)
Warning:
• Attach the electric component cover securely. If it is attached incorrectly, it
could result in a fire, electric shock due to dust, water, etc.
• Use the specified indoor/outdoor unit connecting cable to connect the indoor
and outdoor units and fix the cable to the terminal block securely so that no
stress is applied to the connecting section of the terminal block. Incomplete
connection or fixing of the cable could result in a fire.
