When performing electrical and earthing works,
be sure to comply with the 'technical standards of
electrical installations' and the 'wiring regulations'
in the local regulations.
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)
(
09/12
).
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.)
