- Install the main unit away from noise sources.
Installation of Main Unit Box and Panel
The main unit box can be mounted either from the front or from the rear.
When Installing from the Front
-
Since the left and right mounting screws are attached close to each other, please drill the left and right dimensions as accurately as possible.
-
Connect the TU2C-LINK cable, AC adapter, and LAN cable to the main unit.
-
Fit the main unit on to the wall and switch board.
-
Insert a flat head screwdriver, etc. into the groove on the left and right of the bottom of the panel.
There will be a snapping sound and the panel will come off.
REQUIREMENT
• Just insert the screwdriver and do not twist it.
• To prevent the panel from falling, support it during removal. -
Fix the 4 main unit screws.
-
Close the panel by hooking the panel rear to the top of the main unit.
There will be a snapping sound and the panel will be fixed. -
When installation is completed, peel off the transparent film.
-
When Installing from the Rear
-
Although the panel and the main unit box are separated to explain the screw attachment part in an easy to understand manner, it is not necessary to remove the main unit box from the panel in actual installation work.
- Drill four Ø4 holes in the switchboard, wall, etc.
- Fit the main unit on the switch board, wall, etc.
- Fix from the rear of the main unit. Please use the supplied M3 × 8 screws.
- Connect the TU2C-LINK cable, AC adapter, and LAN cable to the main unit.
- When installation is completed, peel off the transparent film.

Termination resistance setting
• RS-485 termination resistance setting ……………….| Set at both ends of the
RS-485 communication line. Set one end at the main unit and the other end at
the interface. The termination resistance of the main unit is already set as a
factory default. Refer to the interface installation manual to set the
termination resistance of the interface.
---|---
• TU2C-LINK / TCC-LINK termination resistance setting ……………………….| <For TCC-
LINK> Leave just 1 line of the termination resistance in the interface board
of the outdoor unit (centre unit) ON, and turn all the others OFF. (Refer to
the wiring diagram attached to the outdoor unit for the position of SW.)
Refer to the manual of each model for the termination resistance setting method.
Shield grounding process

|---|---|
| • TU2C-LINK communication line shielded wire …… | When using the system |
controller with one unit, open the shielded wire of the TU2C-LINK communication line and perform insulation processing. When using the system controller with multiple units, connect the shield of the TU2C-LINK communication line to the closed end and open the shield at the final end of the system controller to perform insulation processing. Perform TU2C-LINK communication line shield grounding on the air conditioner side.
REQUIREMENT
- Be sure to install a circuit breaker or all-pole isolating switch (with a contact breaking distance of at least 3 mm) on the primary side of the power supply.
- Fasten the screws to the terminal block with torque of 0.5 N·m.

• Connection to External Devices
Example of connection to external equipment which is connected to digital
input/output terminal.
* Wire the
cables so that the user does not touch the power supply directly.
- On the external device side, use a basically insulated power circuit and place it in a location where the user cannot touch it.
When using a relay for the circuit on the equipment side of the state output
IMPORTANT
Be sure to connect freewheeling diodes to both ends of the relay coil. (A
relay with a built-in diode is recommended.)
• Wiring connections
This section shows wiring connection examples with the indoor units, power
meter interface, digital I/O interface, and remote monitoring PC.
Air conditioning unit group settings
- Indoor units can be set together for each group unit.
- Groups 1 to 64 correspond to the central control addresses 1 to 64 of the indoor units.
- There is a LINK 1 and a LINK 2 for each TU2C-LINK communication line. If only U Series outdoor units are connected, each line has 128 groups. LINK1 and LINK2 together have 256 groups and 256 zones.
When outdoor units other than the U Series are connected, each line has 64 groups. LINK1 and LINK2 together have 128 groups and 128 zones.
*When an outdoor unit other than the U series is connected to either line, it is set when an outdoor unit other than the U series is connected on both lines.
Interface connection
Connect the power meter interface and the digital I/O interface to the RS-485
cable line. For details of the connection method refer to the interface
installation manual. When using the power meter, connect the power meter
separately for each device.
