3-6-1. Power supply to AG-150A
AG-150A needs DC power supply of 24~30V (M-NET) and 24V; the former is for centralized control transmission use and the
latter is for AG-150A's operating and LAN function use. AG-150A can have power-supply at following 1,2 methods.
3-6-1-1. Power supply unit PAC-SC51KUA is the recommended power supply for AG-150A. The basic scheme is as follows.
For details, please refer to Power supply unit PAC-SC51KUA.
3-6-1-2. Power supply of 30VDC (M-NET) from connector of TB3 of Outdoor unit and PAC-SC51KUA.
AG-150A can also receive power supply from TB3 connector of the R410A or R407C, R22 Outdoor unit.Yet, Outdoor
unit down will lead down to AG-150A too. The kind of connection is possible but not recommended air conditioner
system of multiple Outdoor units. The 24VDC can be supplied at TB3 connector of PAC-SC51KUA.

CAUTION
When applying Charge and/or Peak-cut function on AG-150A, Power Supply Unit (PAC-SC51KUA) is recommended to use. AG-150A is
possible to receive power from the one of the Outdoor units, but there is a risk that the failure of power supply from the Outdoor unit will
cause AG-150A's function-down on the whole system.
At the air conditioner system of multiple Outdoor units, the connector of CN41 is changed to CN40 at only one of the Outdoor units when
TB7 is used to supply power. When the Outdoor unit failed, the connector at another unit can be changed from CN41 to CN40 to recover
the power supply, but remember to change the CN40 back to CN41 at the failed Outdoor unit.
