(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 3 ME 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) Replace the power jumper connector of the control board
from CN41 to CN40 on only one of the outdoor units.
(not required if power to the transmission line for central-
ized control is supplied from a controller with a power-
supply function, such as GB-50ADA)
5) Provide an electrical path to ground for the S terminal on
the terminal block for centralized control on only one of
the outdoor units.
6) A transmission booster must be connected to a system
in which the total number of connected indoor units ex-
ceeds 20.
7) A transmission booster is required in a system to which
more than 16 indoor including one or more indoor units
of the 200 model or above are connected.
8) 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).

Note1 When only the LM adapter is connected,
leave SW2-1 to OFF (as it is).

Note2 LM adapters require the power supply
capacity of single-phase AC 208/230V.
(3) Maximum allowable length
1) Indoor/outdoor transmission line
Same as [5] 3.
2) Transmission line for centralized control
Same as [5] 4.
3) ME remote controller wiring
Maximum overall line length
(0.3 to 1.25mm
m1 10m [32ft]
m2+m3 10m [32ft]
If the standard-supplied cable must be extended, use a
cable with a diameter of 1.25mm
of the cable that exceeds 10m [32ft] must be included in
the maximum indoor-outdoor transmission line distance
described in (1).
When connected to the terminal block on the Simple re-
mote controller, use cables that meet the following cable
size specifications: 0.75 - 1.25 mm
4) Maximum line distance via outdoor unit
2
(1.25mm
or larger)
