ELECTRICAL CONNECTION

WARNING
• Use the specified wires for wiring connect
the terminals. Securely fix them to prevent
external forces applied to the terminals
from affecting the terminals.
Incomplete connection or fixation may cause
a fire or other trouble.
• Connect earth wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect earth wires to gas pipes, water
pipes, lightning conductor or telephone earth
wires.
• Appliance shall be installed in accordance
with national wiring regulations.
Capacity shortage of power circuit or
incomplete installation may cause an electric
shock or a fire.
CAUTION
• For communication line, use wires with the
same type and size. lf each wire has a
different type and size from another one, it
will cause a communication trouble.
• If incorrect / incomplete wiring is carried out, it
will cause an electrical fire or smoke.
• Install an earth leakage breaker that is not
tripped by shock waves. If an earth leakage
breaker is not installed, an electric shock may
be caused.
• Use the cord clamps attached to the product.
• Do not damage or scratch the conductive core
and inner insulator of power and control wires
when peeling them.
• Use the power supply wire and control wires
of specified thickness, type, and protective
devices required.
• Do not connect 208/230V power to the terminal
blocks (Uv (U1)), (Uv (U2)), (A), (B) for control
wiring. (Otherwise, the system will fail.)
• Perform the electric wiring so that it does not
come to contact with the high-temperature
part of the pipe. The coating may melt
resulting in an accident.
REQUIREMENT
• For power supply wiring, strictly conform to the
Local Regulation in each country.
• For wiring of power supply of the outdoor units,
follow the Installation Manual of each outdoor
unit.
• Perform the electric wiring so that it does not
come to contact with the high-temperature part
of the pipe.
The coating may melt resulting in an accident.
• After connecting wires to the terminal blocks,
provide a trap and fix wires with the cord clamp.
• Run the refrigerant piping line and control
wiring line in the same line.
• Do not turn on the power of the indoor unit until
vacuuming of the refrigerant pipes completes.
