• 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 0.89-1.33 lbf•ft [1.2-1.8 N•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 98.42 ft (30m).
CAUTION
Non-circular
• 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.
Non-fitted
• 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
49.21 ft 15 (meters).
• 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.)
