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.
3 Insert both sides of core wire of the power cable into
the connection sleeve.
• Method 1: Push the core wire into the sleeve from
both sides.
• Method 2: Twist the wire cores together and push it
into the sleeve.
Method 1
Connection sleeve
CAUTION
• 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.
