INSTALLATION MANUAL
Digital Inverter Air Conditioner
“1 : 1 Model” Connection Interface
Use for Indoor Unit Only
MODEL : TCB-PCNT30TLE2
[For Installation Professionals]
• Before installation work, please read this manual thoroughly and install the products correctly.
Precaution for safety
WARNING
• Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Perform installation work surely based on this Installation Manual.
Incomplete installation causes an electric shock or a fire.
• Ask an authorized dealer or qualified installation professional to reinstall 1 : 1 Model Connection
Interface.
Incomplete installation causes an electric shock or a fire.
• For an electric work, this Installation Manual shall be referred and exclusive circuit shall be
necessarily used. The used voltage shall be also match with the rated voltage of the product.
If there is capacity shortage of electric circuit or installation work is poor, an electric shock or a fire may be
caused.
CAUTION
• Using the specified wires, surely connect wires so that external force of wire is not applied to connecting
part of the terminals; otherwise disconnection, heating or fire will generate.
• For wiring work, use wires with correct current capacity; otherwise leakage, heating or fire will generate.
• Do not apply an excessive force on the board body, otherwise bending, separation, or disconnection gener-
ates resulted in heating or fire.
• After installation work, execute a test run to confirm there is no trouble.
And also ask the customers to keep this Manual by themselves.

Before Installation
This interface corresponds to the digital inverter air conditioner.
Do not use or connect this interface for other type of air conditioner than the above because the indoor P.C.
boards of other air conditioners differ from one of the digital inverter air conditioner.
Wiring Connection
1. Wiring connection
Remarks
Point 1) When controlling the digital inverter air conditioner collectively, “1 : 1 Model” Connection Interface
(This option) is required.
Point 2) In group control or twin, triple, double twin system, this interface must be connected to Header unit of
the indoor unit. (Connection to follower unit is unavailable.)
Point 3) Connect the central control devices to wires of the central control system.
Point 4) When controlling the digital inverter air conditioner collectively, turn on Bit 1 of SW01 in the line with
the least line address No. (OFF has been set up at shipment from the factory.)
For the digital inverter air conditioner, re-setup of the address from the wired remote con-
troller is required after automatic addressing.

2. Wire Specifications
• Wire is 2-core and non-polarity.
• The length is same to wire length of the central control system.
In case of system mixed with VRF type, the length includes all length of control wiring between indoor unit and
outdoor units at VRFside.
• To prevent noise defect, use 2-core shield wire.
• Connect shield wires with closed-terminal connection and apply open process (insulation process) to the last
termination. For grounding (earth), perform grounding with one point at indoor unit side. (During central control
for digital inverter air conditioner only)
Remarks
Point 1) Closed terminal connection of shield wire (Connection of connecting parts of each indoor unit)
Point 2) Apply open process (insulation process) to the last termination.
Point 3) For grounding (earth), perform grounding with one point at indoor unit side.

For details, refer to installation procedure for each model.
• Parts encircled with chain line are accessories
attached to this product.
•???? indicates control P.C. board, and indi-
cates terminal block (Characters inside of mark
indicate terminal number.)
• There is no polarity for wire connection to terminal
blocks U3 and U4.
(NOTE)
Do not apply voltage to terminals U3 and U4.
If applying voltage to U3 or U4 terminal by mistake,
fusing occurs to protect terminals.
After checking wires, exchange connection of con-
necting connector on “1 : 1 Model” Connection Inter-
face board from CN40 (Blue) to the spare CN44
(Brown).

Setup of P.C. Board Switch
When the units controlled collectively are all digital inverter air conditioners, it is required to set up the terminator
resistor. (Collective control for units without VRF type air conditioner)
• Using SW01, set up the terminator resistor.
• Set up the terminator resistor to only interface connected to the indoor unit in the line with the least line
address No.
