* This figure omits the power supply line and only shows the transmission line.
<Restrictions>
Maximum of 50 units per AE-200E/AE-50E/EW-50E/AG-150A/EB-50GU-J
However, the number of units that can be connected to a AE-200E/AE-50E/EW-50E/AG-150A/EB-50GU-J is up to 50 including this
device, an indoor unit, LOSSNAY unit, etc.
NOTE
• For the shield ground of the M-NET centralized control line, use single-point grounding at the power unit for
the transmission line.
However, when supplying electric power to the M-NET centralized control line from the R410A series outdoor
unit
*1
without using a power supply unit for the transmission line, use single-point grounding at the TB7 of that
outdoor unit. *1 : Except PUMY model.
Furthermore, when connecting the M-NET transmission line of this device to the M-NET indoor control line,
use grounding at the TB3 for each outdoor unit system.
• If the M-NET transmission line of this device is connected to an M-NET indoor control line and the outdoor
unit is down because, for example, the power supply is interrupted for servicing or there is a failure, the AI
controller cannot be set and monitored from the system controller.
• The sensor connected to the AI controller can only be monitored from AE-200E/AE-50E/EW-50E/AG-150A/
EB-50GU-J Web browser and TG-2000A.
The sensor can be monitored from the AE-200E/AE-50E/AG-150A LCD.
