a. Address settings are the same as for wiring connection examples A and B.
b. Let the number of indoor units and remote control units connected be within the limit for the number of units shown in the following table for
the total of the number of units connected between the variable capacity unit (OC) and the transmission booster (RP) N
1
and the number of
units connected after the transmission booster (RP) N
2
.
c. Connect the power supply ground to the transmission booster (RP) securely.
Connect the transmission lines of the outdoor unit side to terminals A and B of transmission line terminal block 1 (TB2) of the transmission
booster (RP).
Connect the transmission lines of the expansion indoor unit side to terminals A and B of the of transmission line terminal block 2 (TB3) of the
transmission booster (RP).
The number of indoor units and the total number of remote controllers is displayed within the parenthesis (
).
*1 If even one unit that is higher than 200 exists in the cooling system, the maximum capacity will be “200 or higher”.

Prohibited items
•
Do not mistake the connection locations of transmission booster (RP) transmission line terminal block 1 (TB2) and transmission line termi-
nal block 2 (TB3). (Operation will not be normal in such a case.)
•
Do not connect the S terminals of transmission line terminal block 1 (TB2) and transmission line terminal block 2 (TB3) of the transmission
booster (RP) together.
