 Power supply wire and communication wires specifications
Power supply wire and communication wires are locally procured.
For the power supply specifications, follow to the table below. If capacity is little, it is dangerous because overheat
or burnout may be caused.
For specifications of the power capacity of the outdoor unit and the power supply wires, refer to the Installation
Manual attached to the outdoor unit.
Indoor unit power supply
• For the power supply of the indoor unit, prepare the exclusive power supply separated from that of the outdoor
unit.
• Arrange the power supply, circuit breaker, and main switch of the indoor unit connected to the same outdoor unit
so that they are commonly used.
• Power supply wire specification: Cable 3-core 2.5 mm², in conformity with Design 60245 IEC 57 .
 Power supply
Control wiring, Central controller wiring
• 2-core with non-polarity wires are used for the Control wiring between indoor unit and outdoor unit and Central
controller wiring.
• To prevent noise trouble, use 2-core shield wire.
 Communication line
TU2C-Link models (U series) can be combined with TCC-Link models (other than U series).
For details of communication type, refer to the following table.
Communication type and model names
U series outdoor unit: SMMS-u (MMY-MUP )
Other than U series outdoor unit: SMMS-i, SMMS-e etc. (MMY-MAP )
Power supply
220 V - 240 V, 50 Hz
220 V, 60 Hz
Power supply switch / circuit breaker or power supply wiring / fuse rating for indoor units should be selected by
the accumulated total current values of the indoor units.

<In the case of combining with outdoor units of Super Modular Multi System u series (SMMS-u)>
Follow the wiring specifications in the table below even when units other than U series are mixed in the indoor units
and remote controllers to be connected.
•
U (v, h, c)
line means of control wiring.
Uv
line: Between indoor and outdoor units.
Uh
line: Central control line.
Uc
line: Between outdoor and outdoor units.
•
Uv
line and
Uc
line are independent from another refrigerant line. Total length of
Uv
and
Uc
lines
(L3 + L4)
in each refrigerant line is up to 1000 m.
REQUIREMENT
For connection of Uv line / Uc line or Uh line, wire each line using wires with the same type and size. If different
wire types and size are mixed and used in a system, communication trouble is caused.
Uv line and Uc line (L2, L3, L4)
(2-core shield wire, non-polarity)
Wire size: 1.0 to 1.5 mm² (Up to 1000 m)
Uh line (L1)
(2-core shield wire, non-polarity)
Wire size:
1.0 to 1.5 mm² (Up to 1000 m)
2.0 mm² (Up to 2000 m)
