Attach a round crimp terminal to each wire of the power line and signal line.
Loosen the screws with a screwdriver, insert the digital I/O cable, and tighten the screws securely.
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.)
- For TU2C-LINK: For the central control wiring (Uh line), set the termination resistance that is farthest away on the wiring between this central controller and the other unit (VRF, light commercial, air to air heat exchanger, general purpose control interface, air to water heat pump) to ON.
Refer to the manual of each model for the termination resistance setting method.
Diagrams show termination resistance settings: ON, OFF, ON.
Shield grounding process
- RS-485 cable wire shielded wire: Connect to the FG terminal block.
- 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.

The TU2C-LINK model (U series) can be used together with previous models (other than U series). For details of the model and communication method, see the following table.
| Communication method | TU2C-LINK (U series) | TCC-LINK (other than U series) |
|---|---|---|
| Outdoor unit | MMY-MUP*** U series model | Other than on the left (MMY-MAP***, MCY-MAP***, etc.) |
| Indoor unit | MM*-UP*** U series model | Other than on the left (MM*-AP***, etc.) |
| Wired remote controller receiver | RBC-AMSU** U series model | Other than on the left |

| Wire types that can be used | Shielded wire |
REQUIREMENT
When wiring the control wiring between indoor and outdoor units (Uv line)/control wiring between outdoor units (Uc line) and the central control wiring (Uh line), use the same wire type and diameter for each line. Using a mixture of different wire types and diameters may cause a communication error.
System diagram: A diagram illustrates the system connections for various equipment types (Light Commercial, Air to Water Heat Pump, Air to air heat exchanger, General purpose equipment control interface) with U series and non-U series components. 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. This section shows wiring connection examples with the indoor units, power meter interface, digital I/O interface, and remote monitoring PC. 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. A system diagram shows the network configuration with the System Controller, Hub, Remote monitoring PC, Power meter interface, and Digital I/O interface, connected via LAN and RS-485. NOTE When you remove the rear panel of this Unit, there is SW100 which is the termination resistance between LINK1 and LINK2 terminals. For the central control wiring (Uh line), set the two terminating resistors at both ends of the wiring between this Unit and the air conditioner to ON "Close" as much as possible.Connection to External Devices
