2. Wire Specifications
• Wire is 2-core and non-polarity.
• The length is same to wire length of the central control system.
In case of system mixed with VRF type, the length includes all length of control wiring between indoor unit and
outdoor units at VRFside.
• To prevent noise defect, use 2-core shield wire.
• Connect shield wires with closed-terminal connection and apply open process (insulation process) to the last
termination. For grounding (earth), perform grounding with one point at indoor unit side. (During central control
for digital inverter air conditioner only)
Remarks
Point 1) Closed terminal connection of shield wire (Connection of connecting parts of each indoor unit)
Point 2) Apply open process (insulation process) to the last termination.
Point 3) For grounding (earth), perform grounding with one point at indoor unit side.

3. Wiring Diagram with Indoor Control P.C. Board
For details, refer to installation procedure for each model.
• Parts encircled with chain line are accessories
attached to this product.
• ???? indicates control P.C. board, and indi-
cates terminal block (Characters inside of mark
indicate terminal number.)
• There is no polarity for wire connection to terminal
blocks U3 and U4.
(NOTE)
Do not apply voltage to terminals U3 and U4.
If applying voltage to U3 or U4 terminal by mistake,
fusing occurs to protect terminals.
After checking wires, exchange connection of con-
necting connector on “1 : 1 Model” Connection Inter-
face board from CN40 (Blue) to the spare CN44
(Brown).
