CAUTION
•
Connect the wires firmly so that wires cannot be pulled
out. Loose wires can cause the connection to overheat.
Each circular terminal must match the size of its
corresponding screw in the terminal block.
CAUTION
•
For the terminal block wiring, use a wire with a
ring terminal socket only. Regular wires without a
ring terminal socket may become a hazard as the
connections may loosen during operation.
For the product that uses the R-32 refrigerant, be cautious not
to generate a spark by keeping the following requirements:
‐
Do not remove the fuses with power on.
‐
Do not disconnect the power plug from the wall
outlet with power on.
‐
It is recommended to locate the outlet in a high
position. Place the cords so that they are not tangled.

Tighten the terminal block screw.

In Step 2-2, step 3 you determined the exit position for the
piping bundle. If using the left, right, or bottom exits, pass
the cables through the selected knockout.
NOTE
•
Power supply cords of parts of appliances for outdoor
use shall not be lighter than polychloroprene sheathed
flexible cord. (Code designation IEC: 60245 IEC66/

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.
