1 N·m = 10 kgf·cm
•
Power supply cords of parts of appliances for outdoor
use shall not be lighter than polychloroprene sheathed
flexible cord. (Code designation IEC:60245 IEC 57 /
CENELEC: H05RN-F or IEC:60245 IEC 66 / CENELEC:
H07RN-F)
•
Since it has the external power supply, refer to the
outdoor unit installation manual for MAIN POWER.
CAUTION
•
When installing the indoor unit in a computer room or
a server room, use the double shielded communication
cable (tape aluminum / polyester braid + copper) of
FROHH2R type.

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.
