(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 the section "4-3. Wiring System Diagram."
(6) • Connecting cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed 5 or 3 *1.5 mm
flexible cord. Type designation 60245 IEC57 (H05RN-F, GP85PCP etc.) or heavier cord.
• 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)
Loose wiring may cause the terminal to overheat or result in unit malfunction.
WARNING
A fire hazard may also exist.
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 Terminal"
and fasten the wire securely with the fixing screw of the terminal board.
How to Connect Wiring to Terminal
■ For stranded wiring
(1) Cut the wire end with cutting pliers, then strip the insulation
to expose the stranded wiring about 10 mm and tightly
twist the wire ends.

(2) Using a Phillips head screwdriver, remove the terminal
screw(s) on the terminal board.
(3) Using a ring connector fastener or pliers, securely clamp
each stripped wire end with a ring pressure terminal.
(4) Place the ring pressure terminal, and replace and tighten
the removed terminal screw using a screwdriver.

■ Examples of shield wires
(1) Remove cable coat not to scratch braided shield.
(2) Unbraid the braided shield carefully and twist the
unbraided shield wires tightly together. Insulate the shield
wires by covering them with an insulation tube or wrapping
insulation tape around them.
(3) Remove coat of signal wire.
(4) Attach ring pressure terminals to the signal wires and the
shield wires insulated in Step (2).
■ Earth wire for power supply
The earth wire should be longer than the other lead wires for
electrical safety.
