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.
(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.

(5) Use shielded wires for inter-unit control wiring (C) and ground
the shield on both sides, otherwise misoperation from noise
may occur. Connect wiring as shown in Section “4-3. Wiring
System Diagrams”.
(6) • Use the standard power supply cables for Europe (such as H05RN-F or H07RN-F which conform to CENELEC (HAR)
rating specifications) or use the cables based on IEC standard. (60245 IEC57, 60245 IEC66)
• Connecting cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed 5 or 3 *1.5 mm

flexible cord. Type designation 60245 IEC 57 (H05RN-F, GP85PCP etc.) or heavier cord.
WARNING
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.
