1 Precautions for Safety
• Read these “Precautions for Safety” carefully before installation.
• The precautions described below include important items regarding safety. Observe them without fail.
• After the installation work, perform a trial operation to check for any problem. Explain how to use and maintain
the unit to the customer. Ask the customer to keep this Installation Manual.
WARNING
• Ask an authorized dealer or qualified installation professional to install or reinstall the TCB-IFMB640TLE.
Improper installation may result in electric shock or fire.
• Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
• Perform installation work properly according to this Installation Manual.
Improper installation may result in electric shock or fire.

Any modification may cause a malfunction, resulting in overheating or fire.
CAUTION
• Perform wiring correctly in accordance with the specified the current capacity.
Failure to do so may result in short-circuit, overheating, or fire.
• Connect the specified cables for the terminals securely to prevent external forces from affecting them.
Failure to do so may result in disconnection, overheating, or fire.

Wiring Connection
The following describes a connection example when using two or more TCS-NET Relay Interface units.
Terminator resistor setting (See “6 Setting” for the setting method.)
• Set the RS-485 terminator resistor to “Resistor set (120 ohm)” for No.1 (relay interface address SW1=1) TCSNET Relay Interface unit, and set to “open” for other units.
• Set the TCC-LINK terminator resistor to “open” as it is set on the air conditioner side.
Shield earthing
• The shield of RS-485 signal wires should be connected at closed end, and the terminal end should be open and
insulated. The shield earth of the RS-485 signal wires should be single-point earth at the host system.
The shield earth of the RS-485 signal wires should be single-point earth.
• The shield of TCC-LINK signal lines should be connected at the closed end, and the TCS-NET Relay Interface
terminal end should be open and insulated. Earth is connected on the air conditioner side.

Set the TCS-NET Relay Interface address with
SW1. Assign 1 to 8 to each address to avoid
duplication.
CAUTION: The SW1 setting is read when the
power is turned on. Push the reset switch SW7
after changing the address.

6 Setting
The following settings are necessary to use TCS-NET Relay Interface.
• SW1 TCS-NET Relay Interface address set switch
When two or more TCS-NET Relay Interface are used, set a different address for SW1 to avoid address
duplication.
Assign addresses in an ascending order.
CAUTION
• Set relay interface addresses according to the air conditioner address table.
For the relay interface whose address SW1=1, perform terminator resistor setting.
• When the SW1 setting has been changed, push the reset switch SW7. The new address setting is read.
• SW2 Test switch
• SW3 Test switch
• SW4 Test switch
Not used during operation.
Set these switches to zero (0) or “all OFF”.
• SW5 RS-485 terminator resistor select switch
Set “Resistor set (120 ohm)” only when the
relay interface address SW=1, and set “open”
for other relay interfaces.

7 Trial Operation Check
Before starting trial operation
Complete the air conditioner trial operation.
Turn on the power of the TCS-NET Relay Interface after all cable connections and settings are completed.
Then turn on power of the Touch Screen Controller or intelligent Server.
