Reinstallation must be performed by professionals.
improper installation may lead to electric shock or fire.

Do not disassemble your air conditioner at will.
A random disassembly may cause abnormal operation or heating, which may result in fire.

CAUTION

Once flammable gases are leaked and left around the wire controller, fire may occure.

The wiring should adapt to the wire controller current.
Otherwise, electric leakage or heating may occur and result in fire.

The specified cables shall be applied in the wiring. No external force may
be applied to the terminal.
Otherwise, wire cut and heating may occur and result in fire.

Do not place the wired remote controller near the lamps, to avoid the remote signal of the controller to be disturbed. (refer to the right figure)

1        2-core shielded cable                1                                RVVP-0.5mm2x2                  Max 350m

2        86 Electrician box 1

3       Wiring Tube(Insulating Sleeve 1

and Tightening Screw)

4       KNX power module 1

5      Communicate module 1

Note to installation of MD-KNX-01:

1. One KNX module can only connect with one indoor unit;The KNX module should connect to indoor XYE ports, can’t connect to outdoor XYE ports.
2. Circuit of MD-KNX-01 is low voltage circuit. Never connect it with a standard 220V/380V circuit  or put it into a same Wiring Tube with the circuit.
3. Do not attempt to extend the shield cable by cutting, if it is necessary, use Terminal Connection Block to connect.
4. After finishing connection, do not use Megger to have the insulation check to the signal wire.
5. The default physical address of the MD-KNX-01 is 15.15.255,If there are two or more KNX modules, then the physical addresses can not repeat.The physical address can be changed by ETS software.
