NOTE
࡛
Each wire is labelled with the corresponding terminal
number.
࡛
Use shield cable (Category 5; less than 50pF/m) for
noisy environmental site.
࡛
Power supply cords of parts of appliances for outdoor
use shall not be lighter than polychloroprene
sheathed flexible cord.
࡛
Power & Communication cable shall not exceed
98.42ft(30m).
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 due
to overheating of the electrical contact during
installation.
࡛
If you need to extend the pipe, be sure to extend
the cable, too. The maximum length of each of the
cable and pipe used should not exceed 49.2ft (15 m)
(

).
࡛
Do not connect two or more different cables to
extend the length. This connection may cause fire.
࡛
Each circular terminal must match the size of its
corresponding screw in the terminal block.
࡛
After connecting the cables, make sure that terminal
numbers on the indoor and outdoor units match.
࡛
Ensure that power and communication cables are
separated, they must not be in the same cable.
WARNING
࡛
Connect the wires firmly so that wires cannot be
pulled out easily. (If they are loose, it could cause
burn-out of the wires.)
