CAUTION
(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. 1-10)
(3) If branching the inter-unit control wiring, the number of branch points should be 16 or fewer.
(Branches less than 1 m are not included in the total branch number.) (Fig. 1-11)
