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.
