System with a Connection of System Controller to Centralized Control
Transmission Line
(1) Sample control wiring
An example of a system in which a system controller is connected to the transmission cable for the centralized control system
and the power is supplied from the outdoor unit
(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 (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 termi-
nal (
) on the terminal block for transmission line for central-
ized 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
200 model or above is connected) are connected.
Refer to the DATABOOK for further information about how
many booster units are required for a given system.
7) When a power supply unit is connected to the transmission 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 2-7-3
2) Transmission line for centralized control
L31+L32(L21) 200m
[656ft]
3) MA remote controller wiring
Same as 2-7-1
4) Maximum line distance via outdoor unit
(1.25mm
