6. Precautions When Designing M-NET
Systems
6.1 M-NET Transmission Cable Power Supply
On an M-NET system, the remote controller or central controller operate on power from the transmission cable. Accordingly,
there is need to provide power to the transmission cable.
Two systems are available for supplying power: the central system is supplied by a power supply unit; the indoor unit system is
supplied by an outdoor unit. The Lossnay unit and the Lossnay remote controller can be connected to either system.
6.2 Restrictions When the Lossnay Units are Con-
nected to the Central Controller M-NET Trans-
mission Cable
The power supply unit has limited capacity; therefore, the number of Lossnay remote controllers is restricted when the Lossnay
M-NET remote controllers and Lossnay units are connected to the centralized controller transmission cable. The restriction does
not apply to Lossnay and G-50A units that do not receive power from the centralized controller transmission cable.

Transmission Booster
PAC-SF46EPA
• If a larger number of Lossnay remote controllers than that shown above is connected due to the addition a power supply unit
(PAC-SC50KUA, PAC-SC51KUA), a transmission booster (PAC-SF46EPA) is necessary.
• Transmission Booster (PAC-SF46EPA) can be used without a power supply unit (PAC-SC50KUA, PAC-SC51KUA) if TB2
(outdoor unit side) is opened, and the M-NET transmission cable is connected to TB3 (additional indoor unit side).
