5.1. Indoor unit (Fig. 5-1, Fig. 5-2, Fig. 5-3)
1. Loosen the two screws securing the electric component cover, and then slide and
remove the cover.
2. Route each cable through the wiring intake into the electric component box. (Procure
power supply cable and control cable locally.)
3. Securely connect the power supply cable and control cable to the terminal blocks.
4. Secure the wires with the cable straps inside the electric component box. Secure
the wires with cable straps as cushioning components so that no stress is applied
to the connecting sections of the terminal block when tension is generated.
5. Attach the electric component cover as it was.
• Do not allow slackening of the terminal screws.
• Always install earth.
(Earth cable dia: Thicker than 1.6 mm)
• Fix power supply cable and control cable to electric component box by using buffer
bushing for tensile force. (PG connection or the like.)

Warning:
• Insert hook the electric component cover into the bent support on the electric
component box and attach the 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.
