• Since it has the external power supply, refer to the
outdoor unit installation manual for MAIN POWER.
CAUTION
• When installing the indoor unit in a computer room or
a server room, use the double shielded communication
cable (tape aluminum / polyester braid + copper) of

As shown in the figure, peel off the shields from the
rubber and wire of the power cable.
• Peel off 20 mm of cable shields from the pre-
installed tube.
CAUTION
• For information about the power cable specifications
for indoor and outdoor units, refer to the installation
manual.
• After peeling off cable wires from the pre-installed
tube, insert a contraction tube.
• If cable wires are connected without using connecting
sleeves, their contact area becomes reduced, or
corrosion develops on the outer surfaces of the wires
(copper wires) over a long time. This may cause an
increase of resistance(reduction of passing current)
and consequently may result in a fire.
