ELECTRICAL WORK
WARNING
1.
Using the specified wires, ensure that the wires
are connected, and fix wires securely so that
the external tension to the wires does not affect
the connecting part of the terminals.
Incomplete connection or fixation may cause a fire,
etc.
2.
Be sure to connect the earth wire (grounding
work).
Incomplete grounding may lead to electric
shock.
Do not connect ground wires to gas pipes, water
pipes, lightning rods or ground wires for telephone
wires.
3.
The appliance shall be installed in accordance
with national wiring regulations.
Capacity shortages of the power circuit or an
incomplete installation may cause an electric shock
or fire.
CAUTION
• Wrong wiring may cause a burn-out of some electrical
parts.
• Be sure to use the cord clamps attached to the
product.
• Do not damage or scratch the conductive core or inner
insulator of the power and inter-connecting wires when
peeling them.
• Use the power and Inter-connecting wires with
specified thicknesses, specified types and protective
devices required.
• Remove the panel, and you can see electric parts on
the front side.
• A metal pipe can be installed through the hole for
wiring. If the hole size does not fit the wiring pipe to be
used, drill the hole again to an appropriate size.
• Be sure to clamp the power wires and indoor/outdoor
connecting wires with a banding band along the
connecting pipe so that the wires do not touch the
compressor or discharge pipe.
(The compressor and the discharge pipe become hot.)
Furthermore, be sure to secure these wires with the pipe
valve fixing plate and cord clamps stored in the electric
parts box.

Wiring between Indoor Unit and Outdoor Unit
The dashed lines show on-site wiring.
•
Connect the indoor/outdoor connecting wires to the identical terminal numbers on the terminal block of each unit.
Incorrect connection may cause a failure.
For the air conditioner, connect a power wire with the following specifications.

How to wire
1.
Connect the connecting wire to the terminal as
identified with their respective numbers on the
terminal block of the indoor and outdoor units.
H07 RN-F or 60245 IEC 66 (1.5 mm
2
or more)
2.
When connecting the connecting wire to the outdoor
unit terminal, prevent water from coming into the
outdoor unit.
3.
Insulate the unsheathed cords (conductors) with
electrical insulation tape. Process them so that they
do not touch any electrical or metal parts.
4.
For interconnecting wires, do not use a wire joined
to another on the way.
Use wires long enough to cover the entire length.
5.
Wiring connections differ in conformance to
EMC standards, depending whether the system
is single, twin or triple. Connect wires according
to respective instructions.
CAUTION
• An installation fuse must be used for the power supply
line of this air conditioner.
• Incorrect/incomplete wiring may lead to an electrical
fire or smoke.
• Prepare an exclusive power supply for the air
conditioner.
• This product can be connected to the mains power.
Fixed wire connections:
A switch that disconnects all poles and has a contact
separation of at least 3 mm must be incorporated in
the fixed wiring.
