•
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.
• Tighten the terminal block screw to 1.2-1.8 N•m (1.2-
1.8 kgf•cm).
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. (Code designation IEC: 60227
IEC53/CENELEC: H05VV-F, IEC: 60245 IEC 66/
CENELEC: H07RN-F, IEC: 60245 IEC 57/CENELEC:
H05RN-F)
•
Power & Communication cable shall not exceed 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 15 metres
(

and 30 metres(

✴✴
SS/TC).
•
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.)
