(1) When linking the 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 wiring connection

between outdoor units), do not remove the short plug.

(Branches that are less than 1 m are not included in the total branch number.) (Fig. 5-7)
