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

(2) Cautions
1) ME remote controller and MA remote controller cannot both be con-
nected 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 per-
formed only on one of the outdoor units.
(not required if power to the transmission line for centralized control
is supplied from a controller with a power-supply function, such as
GB-50ADA)
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) When the number of the connected indoor units is as shown in the
table below, one or more transmission boosters (sold separately)
are required.
To connect two transmission boosters, connect them in parallel.
(Observe the maximum number of connectable indoor units that are
listed in the specifications for each outdoor unit.)

are not included in the connected
indoor units

7) When a power supply unit is connected to the transmission
line for centralized control, leave the power jumper connec-
tor on CN41 as it is (factory setting).
(3) Maximum allowable length
1) Indoor/outdoor transmission line
Same as [5] 3.
