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 this device to the M-NET indoor control line, use grounding at the TB3 for each outdoor unit
system.
• If this device is connected to the 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 DIDO controller cannot be controlled from the system controller.
• Controlling the system remote controller, ON/OFF remote controller, and schedule timer is only possible with channel 1 of a
standard terminal.
• When G(B)-50A is connected, monitoring control can only be performed from G(B)-50A Web or TG-2000A. Monitoring control
cannot be performed from the system remote controller, ON/OFF remote controller or schedule timer.
