*2 If PAC-SC51KUA is used to supply power at TB7 side, no power supply need from Outdoor/Heat source unit at TB7, Connector TB3 itself will therefore
have 32.
With the equivalent power consumption values and the equivalent number of units in Table 1 and Table 2, PAC-SF46EPA-G
can be designed into the air-conditioner system to ensure proper system communication according to (A), (B), (C).
(A) Firstly, count from TB3 at TB3 side the total equivalent number of units of Indoor units, ME remote controller, and
System controllers. If the total equivalent number of units reaches 40, a PAC-SF46EPA-G should be set.
(B) Secondly, count from TB7 side to TB3 side the total transmission power consumption. If the total equivalent power
supply reaches 32, a PAC-SF46EPA-G should be set. Yet, if a PAC-SC51KUA or another controller with a built-in pow-
er supply, such as PAC-YG50ECA, is used to supply power at TB7 side, count from TB3 side only.
(C) Thirdly, count from TB7 at TB7 side the total transmission power consumption, If the total equivalent power supply for
only TB7 reaches 6, a PAC-SF46EPA-G should be set. Also, count from TB7 at TB7 side the total equivalent number
of units of System controllers, and so on. If the total equivalent number of units reaches 40, a PAC-SF46EPA-G should
be set.
* The equivalent power supply of S-Series outdoor unit is 12.
* When one or more indoor units listed in Table 3 is connected, subtract 3 from the equivalent power supply.
