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 outdoor unit (OC) and the transmission booster (RP) N
connected after the transmission booster (RP) N
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).
