Precautions for Safety
· Read these "Precautions for Safety" carefully before installation. · The precautions described below include important items regarding safety. · After the installation work, perform a trial operation to check for any problem. [. . . ] · After the installation work, perform a trial operation to check for any problem. Ask the customer to keep this Installation Manual.
WARNING
· Ask an authorized dealer or qualified installation professional to install or reinstall the TCB-IFMB640TLE. · Turn off the main power supply switch or breaker before attempting any electrical work. · Perform installation work properly according to this Installation Manual. Any modification may cause a malfunction, resulting in overheating or fire.
CAUTION
· Perform wiring correctly in accordance with the specified the current capacity. · 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.

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.
