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.
