Electrical connection
WARNING
• Use the specifi ed wires for wiring connect the terminals. Securely fi x them to prevent external forces
applied to the terminals from affecting the terminals.
Incomplete connection or fi xation may cause a fi re or other trouble.
• Connect grounding wire. (grounding work)
x
Incomplete grounding cause an electric shock.
Do not connect grounding wires to gas pipes, water pipes, lightning conductor or telephone grounding 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 fi re.
CAUTION
• The wire size and wire length of the communication line differs depending on the outdoor unit series
to be connected.
• If incorrect / incomplete wiring is carried out, it will cause an electrical fi re 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 insulation of power and control wires when peeling
them.
• Use the power supply wire and control wires of specifi ed thickness, type, and protective devices required.
• Do not connect 208V-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.
• After connecting wires to the terminal blocks, provide a trap and fi x wires with the cord clamp.
• Run the refrigerant piping line and communication line in the same line.
• Do not turn on the power of the indoor unit until vacuuming of the refrigerant pipes completes.
