4.  A system in which a system controller is connected to the transmission line for centralized control and which is pow-
ered from an outdoor unit
(1) Sample control wiring
(2) Cautions
1)   ME remote controller and MA remote controller cannot 
both be connected to the same group of indoor units.
2)   No more than 2 MA remote controllers can be connected 
to a group of indoor units.
3)   Do not connect the terminal blocks (TB5) on the indoor 
units that are connected to different outdoor units with 
each other.
4)   Replacement of male power jumper connector (CN41) 
must be performed only on one of the outdoor units.
5)   Short-circuit the shield terminal (S terminal) and the 
earth terminal ( 
 ) on the terminal block for transmission 
line for centralized control (TB7) on the outdoor unit 
whose power jumper connector is mated with CN40. 
6)   A transmission booster is required in a system to which 
more than 32 indoor units (26 units if one or more indoor 
units of the 72 model or above is connected) are con-
nected.
7)   When a power supply unit is connected to the transmis-
sion line for centralized control, leave the power jumper 
connector on CN41 as it is (factory setting). 
(3)  Maximum allowable length
1)   Indoor/outdoor transmission line
Same as [5] 3.
2)   Transmission line for centralized control
L31+L32(L21) 200m 
[656ft]
3)   MA remote controller wiring
Same as [5] 1.
4)   Maximum line distance via outdoor unit 
(1.25mm
2
 [AWG16] or larger)
L32+L31+L12(L11) 500m 
[1640ft]
L32+L22(L21) 500m 
[1640ft]
L12(L11)+L31+L22(L21) 500m[1640ft]
