Power supply
(1 phase ~/N, 230V,
50Hz)
• The compressor will not operate unless the power supply phase connection is cor-
rect.
• Grounding protection with a no-fuse breaker (earth leakage breaker [ELB]) is usually
installed for D.
• The connection wiring between the outdoor and indoor units can be extended up
to a maximum of 50 meters, and the total extension including the crossover wiring
between rooms is a maximum of 80 m.
A switch with at least 3.5 mm contact separation in each pole shall be provided by

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.
