<Restrictions>
Maximum of 50 units per AG-150A/ G(B)-50A, 24 units per GB-24A.
However, the number of units that can be con
nected to an
AG-150A/G(B)-50
A is up to 50 (to 24 with the GB-24A) 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 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 AG-150A, AG-150/G(B)-50A
