Installation
Step 2.1 Connecting the power and
communication cables (assembly cable)
• 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.
• Tightentheterminalblockscrewto1.2-1.8N•m(12-18
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: 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(**020/025/035******)
/30(**050/068******)metres.
• 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.)
