Wiring specifications
Use the following wiring material to connect signal wires and power supply wires. (Locally procured)
●
NOTE
• TCC-LINK does not have polarity.
• Connect the shield of the TCC-LINK communication line to the earth on the air conditioner side. (One point earth)
CAUTION
• Turn off the power of the air conditioner for safety during installation and removal.
• Connect the power wiring to 220-240 VAC. If you wire the product incorrectly, it will fail.
• Connect the wiring correctly. If you wire the product incorrectly, it will fail.
• Do not wire communication lines (outdoor/indoor transition wiring, central control line wiring) or input/output wiring next to
power supply wiring, etc., or house them in the same metal pipe. Doing so may result in failure.
• Connect the communication line to the outdoor/indoor transition wiring or central control line wiring.
• Do not pass the communication line inside the same conduit as the power supply wiring (220 VAC, etc.), wire with the same
cable, or bring the wiring close to each other.
• For the communication line, use a signal wire that makes it possible to understand the difference between the remote
controller wiring and the power supply wiring.
• Be sure to install a breaker or an all-pole isolating switch on the primary side of the equipment side power supply of TCC-
LINK and digital input/output.

About the shield grounding process
Shield of TCC-LINK communication line
When using a single Central remote
controller, open the shield of the TCC-
LINK communication line and perform
insulation processing.
When using multiple Central remote
controller, connect the shield of the
TCC-LINK communication line to the
closed end, open the shield at the final end
of the Central remote controller and
perform insulation processing.
Perform TCC-LINK communication line
shield grounding on the air conditioner
side.
About terminator resistor setting
TCC-LINK terminator resistor setting
Set on the air conditioner side. The
TCC-LINK terminator resistor is not set
in the Central remote controller. Leave
"open".
