ELECTRICAL WIRING REQUIREMENTS
(a) Precautions regarding electrical wiring
• Use a dedicated branch circuit for the power wiring. Do not share the branch
• Use the specified power cables (type and wiring diameter) for the electrical
WARNING
• For each device, install an overcurrent breaker of the designated capacity. If the
• For each device, install an earth leakage circuit breaker of the designated
CAUTION
• Protective Earthing of the electrical installation shall comply with the
• 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. 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.
• This product is intended for professional use. Permission from the power supplier is required when installing
the U-10MES2E8 outdoor unit that are connected to a 16A distribution network.
 Set the voltage of the GHP outdoor unit 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 of the GHP outdoor unit
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.

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.
