(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.
(When shipping: In shorted condition.)
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. (Fig. 4-3)

(3) Do not install inter-unit control wiring such as star branch wiring. Star branch wiring causes mis-address setting. (Fig. 4-4)
(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.) (Fig. 4-5)

Loose wiring may cause the terminal to overheat or
result in unit malfunction. A fire hazard may also occur.
Therefore, ensure that all wiring is tightly connected.
When connecting each power wire to the terminal, follow the
instructions on "How to connect wiring to the terminal" and
fasten the wire securely with the terminal screw.
