If the length exceeds 10 meters, use a 1.25 mm² shielded wire. The length of this sec-
tion (L

) should be included in the calculation of the maximum length and overall length.
• Never connect together the terminal blocks (TB5) for transmission wires for indoor units (IC) that have been connected to
different outdoor units (OC).
• Set all addresses to ensure that they are not overlapped.
• M-NET remote controller and MA remote controller cannot be connected with the indoor unit of the same group wiring
