• Since it has the external power supply, refer to the
outdoor unit installation manual for MAIN POWER.
CAUTION

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.
