ELECTRICAL WORK
For the air conditioner that has no power cord.
NOTE:
For selection and connection method of the power supply
cords, refer to the details in the Installation Manual of the
outdoor unit.
CAUTIONS
• Use a circuit breaker of a type that is not tripped by
shock waves.
• If incorrect/incomplete wiring is carried out, it will
cause an electrical fire or smoke.
• Prepare the power supply for exclusive use with the
air conditioner.
• This product can be connected to the mains.
Connection to fixed wiring :
A switch or circuit breaker which disconnects all
poles and has a contact separation of at least 3 mm
must be incorporate in the fixed wiring.
An approved short circuit breaker or switches must
be used.
*
(A breaker having a sensitivity of approximately
0.1 second or less and a capacity of approxi-
mately 30 mA is usually used.)
• Be sure to use the cord clamps specified positions
with attached to the product.
• Do not damage or scratch the conductive core and
inner insulator of power and inter-connecting cables
when peeling them.
• Be sure to comply with local cords on running the
wire from outdoor unit to indoor unit (size of wire
and wiring method etc.)
• Use the power cord and Inter-connecting cable with
specified thickness, specified type, and protective
devices specified.
How to wire
1. Connect the connecting cable to the terminal as
identified with their respective matched numbers on the
terminal block of indoor and outdoor unit.
H07 RN-F or 245 IEC 66 (1.0 mm
2
)
2. When connecting the connecting cable to the outdoor
unit terminal, prevent water coming in the outdoor unit.
3. Insulate the unused cords (conductors) stripped the
sheath of connecting cable with PVC tape.
Process them so that they do not touch any electrical
or metal parts.
4. For inter-unit wiring, do not use a cut wire jointed to
another on the way.
Cabling
1. As shown in the figure, remove a screw
and then
remove cover of the terminal block.
2. Remove two screws
‚ and pull the parts box while
lifting up it. If an incomplete connection is done, a
contact failure may be caused and resulted in a danger
of an electric shock and so on.
Work under condition that the parts box is loosened
Correct way
Make a loop on the cable for margin of the length so that
the electric parts box can be taken out during servicing.

3. Strip wire ends (10 mm).
4. Match wire colors with terminal numbers on indoor and
outdoor units’ terminal blocks and firmly screw wires to
the corresponding terminals.
5. Connect the ground wires to the corresponding
terminals.
6. Fix the cable with cord clamp.
7. Fix cover of the parts box and the terminal block surely
with the fixing screws.
Make a loop.
