* This figure omits the power supply line and only shows the transmission line.
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 without
using a power supply unit for the transmission line, use single-point grounding at the TB7 of that outdoor unit.
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 G(B)-50A Web browser and TG-2000A. The sensor
cannot be monitored from the G-50A LCD.
