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. Follow the Owner's
Manual to explain how to use and maintain the unit to the customer. Ask the customer to keep this
Installation Manual together with the Owner's Manual.

WARNING

• Ask an authorized dealer or qualified installation professional to install or reinstall the relay

interface.

Improper installation may result in electric shock or fire.

• Perform installation work properly according to this Installation Manual.

Improper installation may result in electric shock or fire.

• Do not modify the unit.

Any modification may cause a malfunction, resulting in overheating or fire.

CAUTION

• Perform wiring correctly in accordance with specified the current capacity.

Failure to do so may result in short-circuiting, 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 “3 SETTING” for the setting method.)

• Set the RS-485 terminator resistor to “120 ohm” for No.1 (relay interface address SW1=1) TCS-NET

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 intelligent server.
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.

Setting

The following settings are necessary to use TCS-NET Relay Interfaces.

• SW1 TCS-NET Relay Interface address set switch

When two or more TCS-NET Relay Interfaces 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 “120 ohm" only when the relay
interface address SW=1, and set “open”
for other relay interfaces.
