Permissible Length
Prohibited items
• Longest length via outdoor units : L1+L2+L3+L4, L1+L2+L3+L5, L1+L2+L6+L7 [ 500 meters [1450 ft] (1.25 mm² [AWG16])
• Longest transmission cable length : L
1, L3+L4, L3+L5, L6, L2+L6, L7 [ 200 meters [656 ft] (1.25 mm² [AWG16])
• Remote controller cable length : R
1,R2, R2+R3, R4 [ 10 meters [33 ft] (0.5 to 1.25 mm² [AWG20 to AWG16])
If the length exceeds 10 meters [33 ft], use a 1.25 mm² [AWG16] shielded wire. The
length of this section (L
8) 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 wring
