(1) When linking outdoor units in a network (S-net link system), disconnect the terminal extended from the

short plug (CN003, 2P Black, location: right bottom on the outdoor main control PCB) from all outdoor
units except any one of the outdoor units.
(When shipping: In shorted condition.)

Otherwise the communication of S-net link system is not performed. For a system without link (no
connection wiring between outdoor units), do not remove the short plug.

(2) Do not install the inter-unit control wiring in a way that forms a loop. (Fig. 5-13)

branch wiring. Star branch wiring causes mis-address

setting.
