• 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: 60245 IEC66/CENELEC: H07RN-F,
IEC: 60245 IEC57 CENELEC: H05RN-F, IEC: 60227

• 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.

• 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.
• For the product that uses the R-32 refrigerant, be
cautious not to generate a spark by keeping the
following requirements:
– Do not remove the fuses with power on.
– Do not disconnect the power plug from the
wall outlet with power on.
– It is recommended to locate the outlet in a
high position. Place the cords so that they are
not tangled.
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.)
