■ RefertoFig.6-6fromFig.6-2.
<WiringMethodandAddressSettings>
a. Always use shielded wire when making connections between the outdoor unit (OC) and the indoor unit (IC), as well for all OC-OC, and IC-IC wiring intervals.
b. UsefeedwiringtoconnectterminalsM1andM2andthegroundterminalonthetransmissioncableterminalblock(TB3)ofeachoutdoorunit(OC)toterminalsM1,M2
and terminal S on the transmission cable block of the indoor unit (IC).
c. Connect terminals 1 (M1) and 2 (M2) on the transmission cable terminal block of the indoor unit (IC) that has the most recent address within the same group to the terminal
block on the remote controller (RC).
d. Connect together terminals M1, M2 and terminal S on the terminal block for centralized control (TB7) for the outdoor unit (OC).
e. ThejumperconnectorCN41onthecontrolpaneldoesnotchange.
f.
Connect shield ground of the indoor units transmission line to the shield (S) terminal of (TB3) and also connect (S) terminal to the screw (E or F) using attached lead wire.
Connect shield ground of the line between outdoor units and the centralized control system transmission line to the shield (S) terminal of (TB7).
g. Set the address setting switch as follows.
Unit Range Setting Method
M-IC (Main) 01 to 50 Usethemostrecentaddresswithinthesamegroupofindoorunits
M-IC (Sub) 01 to 50
Useanaddress,otherthanthatoftheIC(Main)fromamongtheunitswithinthesamegroupofindoorunits.Thismustbe
in sequence with the IC (Main)
Outdoor unit 51 to 100

* The address automatically becomes “100” if it is set as “01 - 50”.
M-NETRC(Main)*1 101 to 150 Set at an IC (Main) address within the same group plus 100
M-NETRC(Sub)*1 151 to 200 Set at an IC (Main) address within the same group plus 150
MA RC — Unnecessaryaddresssetting(Necessarymain/subsetting)
*1 An ME remote controller cannot be connected to a system that contains a branch box.
