(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 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)
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)
Provide an electrical path to ground for the S terminal on the ter-
minal block for centralized control (TB7) on only one of the out-
door units.
6)
A transmission booster must be connected to a system in which
the total number of connected indoor units exceeds 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.
Refer to the DATABOOK for further information about how
many booster units are required for a given system.

Note1 When only the LM adapter is connected,
leave SW5-1 to OFF (as it is).
Note2 LM adapters require the power supply
capacity of single-phase AC 220/240V.
for centralized control, leave the power jumper connector on
CN41 as it is (factory setting).

If the standard-supplied cable must be extended, use a cable
with a diameter of 1.25mm
that exceeds 10m [32ft] must be included in the maximum in-
door-outdoor transmission line distance described in 1).
*When connected to the terminal block on the Simple remote
controller, use cables that meet the following cable size specifi-
cations: 0.75 - 1.25 mm
