Table 2 The equivalent power supply
*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. Not applicable to the PUMY model.
*1 AE-200E/AE-50E/EW-50E has a built-in function to supply power to the M-NET transmission line. The amount of power that an
AE-200E or an AE-50E can supply is equivalent to the power required by an MN converter (CMS-MNG-E) that is used for
maintenance. An MN converter is connectable to EW-50E only when the equivalent power consumption is less than 1.5.
With the equivalent power consumption values and the equivalent number of units in Table 1 and Table 2, PAC-SF46EPA 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, OA processing units, ME remote
controller, and System controllers. If the total equivalent number of units reaches 40, a PAC-SF46EPA should be set.
In this case, Indoor units sized P200 and 250 are counted as 2, AT-50B is counted as 5, but MA remote controller(s),
PZ-60DR-E, and PZ-43SMF-E are NOT counted.
(B) Secondly, count from TB7 side to TB3 side the total transmission power consumption. If the total power consumption
reaches 32, a PAC-SF46EPA should be set. Yet, if a PAC-SC51KUA or another controller with a built-in power 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 power consumption reaches
6, a PAC-SF46EPA 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 should be set.

Transmission booster (No.1) should be used, if the total equivalent number of
units of Indoor units, OA processing units and ME remote controllers reaches 40,
(Indoor units sized P200 and 250 are counted as 2, AT-50B is counted as 5);
or if the total equivalent transmission power consumption reaches 32.
Within N2, conditions 1,2 should be followed.
1.The total equivalent number of units of Indoor units,
OA processing units and ME remote controller should
not exceed 40.
*Indoor units sized P200 and 250 are counted as 2,
AT-50B is counted as 5.
2.The total equivalent transmission power consumption
should not exceed 25.
