Installation Procedure
2 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.
