(3) Wiring system Diagram
When No. 4 shielding wire is used, always ground the single wire side of the shielding wire . In addition, using the shielding
wire is helpful to prevent the incorrect connection between 5V DC and 220/240V or 380/415V AC because the
discrimination from the power supply wire is clear.

(2) Precaution in electric wiring.
(a) Use separate power supplies for the outdoor and indoor units respectiveliy (Standard specification)
(b) Signal wiring (for indoor and outdoor units)
Double-core cable with a diameter 0.75 to 2 mm
2
should be used for the signal wires.
Never make the indoor and outdoor connecting signal line use co-axial cable or strand with the
power wiring for indoor and outdoor unit and other ower line.
(Never use a multiconductor wire together with power line. It may cause erroneous operation.)
Do not connect high voltage wires 220/240 V or 380/415 V to signal wires. as these wires are DC 5V. Signal wires
should be connected so that the terminal Nos. conform with each other for between outdoor and between indoor units.
However, they will work properly if different polarities are connected.
(Connect (A) and (A), (B)and (B).)
Do not strand or run the remote control cord with power line, electric line, etc.
The total length of the signal wires Should be 1000m or less.
(c) Individual flow divide controller (Same power supply with the indoor units)
Note (1) Do not misconnect the central flow divide controller signal wire.
