CAUTION
(1) When linking the outdoor units in a network, disconnect the terminal extended from the short plug from
all outdoor units except any one of the outdoor units.

For a system without link (no wiring connection 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.

setting.
(4) If branching the inter-unit control wiring, the number of branch points should be 16 or fewer.
(Branches that are less than 1 m are not included in the total branch number.)
