[For Installation Professionals]
• Before installation work, please read this manual thoroughly and install the products correctly.
CAUTIONS 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 adapters.
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.
MODEL : TCB-PCNT30TLE2
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 excessiv e force on the board body, otherwise bending, separ ation, 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 adapter corresponds to the digital inverter air conditioner.
Do not use or connect this adapter 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 in verter air conditioner collectively, “1 : 1 Model” Connection Interface
(This option) is required.
Point 2) In group control or twin system, this adapter 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
controller is required after automatic addressing.

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 adapter connected to the indoor unit in the line with the least line

Installation Procedure
• For installation of “1 : 1 Model” Connection Interface board and removal of relay wire, be sure to wait for a while
(approx. 1 minute) after turning off the power supplies of the air conditioner and the collective control devices. If not
doing so, “1 : 1 Model” Connection Interface board may be damaged.

Usage
• Refer to Owner’s Manual for the central control devices (TCB-SC642TLE2, TCB-CC163TLE2)
Other Cautions
• In a group operation, be sure to turn on power supplies of all the indoor units in group control. (Within 3 minutes)
When power supply of the Header unit is not turned on, there is a possibility that the Header unit exchanges with
Follow er unit. (If Header unit is exchanged, the central control is unavailable.)
