3-37. Important Note for Wiring 4-Way Cassette Type
Power supply inlet
(1) The power supply inlet is located at the lower area of
the refrigerant tubing side of the unit. The electrical
component box is located at the air intake of the bottom
of the unit.
(2) Before installing the ceiling panel, be sure to carry out
the wiring connection.
(3) Remove the lid located on the bottom of the indoor unit
attaching the electrical component box by unscrewing
the philip head tapping screws (x2).
Tapping screw position
(4) Lead the wires from the power supply inlet to the unit.
Be sure to lead the wires through the power supply inlet.
Make sure that no wire is caught between the indoor unit
and ceiling panel. Otherwise, the unit may cause a fire.
(5) Connect the wires into the terminals through the power
supply inlet for the electrical component box.
Fix the wires with a clamping clip.
(6) Reinstall the lid of the electrical component box in its
original position with paying attention not to have the
wires caught in the lid.
Refer to "4. ELECTRICAL WIRING".

4. ELECTRICAL WIRING

4-1. General Precautions on Wiring
(1) Before wiring, confirm the rated voltage of the unit as
shown on its nameplate, then carry out the wiring closely
following the wiring diagram.
(2) Provide a power outlet to be used exclusively for each unit
and a circuit breaker for overcurrent protection should be
provided in the exclusive line.
(3) To prevent possible hazards from insulation failure, the unit
must be grounded.
(4) Each wiring connection must be done in accordance with
the wiring system diagram. Wrong wiring may cause the
unit to misoperate or become damaged.
(5) Do not allow wiring to touch the refrigerant tubing,
compressor, or any moving parts of the fan.
(6) Unauthorized changes in the internal wiring can be very
dangerous. The manufacturer will accept no responsibility
for any damage or misoperation that occurs as a result of
such unauthorized changes.
(7) Regulations on wire diameters differ from locality to
locality. For field wiring rules, please refer to your LOCAL
ELECTRICAL CODES before beginning.
You must ensure that installation complies with all relevant
rules and regulations.
(8) To prevent malfunction of the air conditioner caused by
electrical noise, care must be taken when wiring as follows:
● The remote control wiring and the inter-unit control wiring
should be wired apart from the inter-unit power wiring.
● Use shielded wires for inter-unit control wiring between units
and ground the shield on both sides.
(9) If the power supply cord of this appliance is damaged,
it must be replaced by a repair shop designated by the
manufacturer, because special-purpose tools are required.

NOTE
(1) Refer to Section 4-2. "Recommended Wire Length
and Wire Diameter for Power Supply System" for the
explanation of "A", "B", "C", "D", "E" and "F" in the above
diagram.
(2) The basic connection diagram of the indoor unit shows the
terminal boards, so the terminal boards in your equipment
may differ from the diagram. (Fig. 4-2)
(3) Refrigerant Circuit (R.C.) address should be set before
turning the power on.
(4) Regarding R.C. address setting, refer to the installation
