Make sure the remote controller wiring, the wiring between
the units, and other electric wiring do not pass through the
same locations outside of the unit, separating them by at

CAUTION FOR WIRING
r The indoor units in the same system can be connected to
the power supply from one branch switch. How ever, selec-
tion of branch switch, branch over current circuit breaker
and wiring size must be according to applicable legislation.
r
For connection to the terminal block, use a ring type crimp
style terminals with insulation sleeve or insulate the wirings
properly.
