[. . . ] · 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 specified the current capacity. Failure to do so may result in short-circuiting, overheating, or fire. [. . . ] 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. 1 Introduction nApplications/Functions/Specifications Applications/Functions/Specifications · Applications The TCS-NET Relay Interface is used to connect air conditioners (with TCC-LINK installed) to the air conditioner control system. · Functions The TCS-NET Relay Interface converts signals between TCC-LINK and RS-485. · Specifications Power supply Current Power consumption Operating temperature/humidity Storage temperature Chassis material Dimensions Mass 220 - 240 V, AC 50/60 Hz 18 mA 2. 4 W 0 to 40 °C, 10 to 90% RH (no condensation) -20 to +60 °C Galvanized sheet metal 0. 8t (no coating) 66 (H) x 170 (W) x 200 (D) mm 1 kg External View 200 1 2 22 78 6- 5. 5 mounting holes 78 22 Parts name Case Case lid Grommet Grommet Grommet for power supply 66 63. 6 Specifications Galvanized sheet metal Galvanized sheet metal C30-SG20A C30-SG20A C30-SG20A 3 4 5 22 78 78 22 2 Bottom side 156 170 Top side 147 Before Installation Check the following package contents.

(total length including 2. 00 mm2, 2000m max. air conditioner area) 2-core shield wires 1. 25 mm2, 500m max. (total length) 2 For RS-485 1 Installation TCS-NET Relay Interface Installation Method and Orientation There are five installation methods for this relay interface as shown below: surface mount and wall mounts. Use the attached screws. No good REQUIREMENT Do not install the unit in any of the following places. · Humid or wet place · Dusty place · Place exposed to direct sunlight · Place where there is a TV set or radio within one meter · Place exposed to rain (outdoors, under eaves, etc. ) Installation Space and Maintenance Space A side space for connecting through cable inlets and an upper space for maintenance must be reserved before installation. CAUTION: The SW1 setting is read when the power is turned on. Push the reset switch SW7 after changing the address. 5 Remote controller Remote controller CAUTION: RS-485 signals A and B have polarity. Be careful when connecting the RS-485 wires. Indoor unit Central remote controller ADDRESS The shield of RS-485 cable should be open and insulated. It is not connected to the terminal block.

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. · SW2 Test switch · SW3 Test switch · SW4 Test switch Not used during operation. Set these switches to zero (0) or "all OFF". [. . . ] · When the SW1 setting has been changed, push the reset switch SW7. · 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.
