ELECTRICAL WIRING REQUIREMENTS
(a) Precautions regarding electrical wiring
• This air conditioner shall be installed in accordance with National Wiring Regulations.
• The product meets the technical requirements of EN/IEC 61000-3-3.
• Provide a power outlet exclusively for each unit, and full disconnection means having a contact separation
by 3 mm in all poles must be incorporated in the fixed wiring in accordance with the wiring rules.
• This device includes an inverter. Use an earth leakage circuit breaker that is suitable for use with an inverter.
• Fasten power cables and indoor/outdoor control cables inside the outdoor unit with wiring clamps. Be sure
that they do not come in contact with any of the following:
(1) Engines, motors, fan blades, and other moving or high-temperature devices or fixtures
(2) Refrigerant tubing, pressure release tubes, or other parts of the refrigerant circuit
(3) Installation brackets or other sharp parts
• Use signal cables for the communications cables (remote controller cables and indoor/outdoor control cables)
which are identifiable as different from the power cables (AC 230 V). In addition, do not run the communications
cables parallel to the power cables.
• Run the A/C power cables and communications cables at least 3 meters distant from any units, antennas, control cables,
or power cables of televisions, radios, stereos, intercoms, computers, word processors, and similar devices.
If they are less than 3 meters away, electrical noise interference may occur.
 Set the voltage prior to a test run.
Set the unit to the voltage that matches the power supply
where it is installed.
Select the voltage setting from 220V, 230V or 240V.
 Setting the Voltage
When making the voltage setting, make sure the electricity
is off at the power source.
Set the voltage by rewiring the red wire that connects (TB3)
and (52S) at the top of the starter motor power supply inside
the electrical box, as shown in the diagram.

• Use a dedicated branch circuit for the power wiring. Do not share the branch circuit
with any other electrical devices. Doing so may result in secondary damage occurring
if the breaker is tripped.
• Use the specified power cables (type and wiring diameter) for the electrical
connections, and connect the cables securely. Run and fasten the cables securely so
that external forces or pressure placed on the cables will not be transmitted to their
connection terminals. Overheating or fire may result if connections or attachment
are not secure.
• For each device, install an overcurrent breaker of the designated capacity. If the
wrong breaker is installed, there is danger of fire resulting from overheating or short
circuit.
• For each device, install an earth leakage circuit breaker of the designated capacity.
(Earth leakage circuit breaker rating: 30 mA, 0.1 s or less)
If an earth leakage circuit breaker is not installed, there is danger of electric shock
or fire.
• Protective Earthing of the electrical installation shall comply with the
national and local wiring/installation requirements.
