ŷ NOTE
ŷ Each wire is labelled with the corresponding terminal
number.
ŷ Use shield cable (Category 5; less than 50pF/m) for
noisy environmental site.
ŷ Power supply cords of parts of appliances for outdoor
use shall not be lighter than polychloroprene sheathed
flexible cord. (Code designation IEC: 60245 IEC 66/
CENELEC: H07RN-F, IEC: 60245 IEC 57/CENELEC:
H05RN-F)
ŷ Power & Communication cable shall not exceed
98.42ft(30m).
CAUTION
ŷ 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.
ŷ 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(15m)
(7709/1277)/98.4ft(30m)(7718/2477).
ŷ Do not connect two or more different cables to extend
the length. This connection may cause fire.
ŷ Each circular terminal must match the size of its
corresponding screw in the terminal block.
ŷ After connecting the cables, make sure that terminal
numbers on the indoor and outdoor units match.
ŷ Ensure that power and communication cables are
separated, they must not be in the same cable.
WARNING
ŷ Connect the wires firmly so that wires cannot be pulled
out easily. (If they are loose, it could cause burn-out of
the wires.)
