(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.
(3) Do not install inter-unit control wiring such as star branch wiring. Star branch wiring causes mis-
address setting.
(4) 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.)
