• Do not connect high voltage wire 380/415V 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).)
