MCA=Minimum circuit ampacity. Stated values are maximum values (see electrical data of combination with indoor units for exact values).
NOTICE
We recommend using solid (single-core) wires. If stranded
wires are used, slightly twist the strands to consolidate the
end of the conductor for either direct use in the terminal
clamp or insertion in a round crimp-style terminal. Details
are described in "Guidelines when connecting the electrical
wiring" in the installer reference guide.

NOTICE
▪ Follow the wiring diagram (delivered with the unit,
located at the inside of the service cover).
▪ Make sure the electrical wiring does NOT obstruct
proper reattachment of the service cover.
