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.
