The length of the communication line (L1+L2+L3) means the total length of the inter-unit wire length
between indoor and outdoor units added with the central control system wire length.

CAUTION
The remote controller wire (Communication line) and AC 208-230V wires cannot be parallel to contact
each other and cannot be stored in the same conduits. If doing so, a trouble may be caused on the
control system due to noise or other factor.
If U series models (TU2C-Link) are combined with models other than U series (TCC-Link), the wiring
specifications and maximum number of connectable indoor units will be changed. Pay attentions to their
communication specifications when carrying out the installation, maintenance, or repair. For its details, refer to
the "Communication line" in 8 Electrical connection.

NOTE
Use copper supply wire.
Use UL wire rated 600V for the power supply.
Use UL wire rated 300V for the remote control wires and control wires.
CAUTION
The remote control wire (Communication line) and AC208 / 230V wires cannot be parallel to contact each
other and cannot be stored in the same conduits. If doing so, a trouble may be caused on the control system
due to noise or other factor.
