1) Refer to the Wiring System Diagrams (See next page) for
the meaning of "A", "B", "C", "D", "E" in the above tables.
2) Inter-Unit Control Wiring (c) has no polarity.
But for other wiring, respect polarity.
Be sure to connect as shown in the Wiring System Diagram.
3) The basic connection diagram of the indoor unit shows the
8P terminal board, so the terminal boards in your equipment
may differ from the diagram.
4) In accordance with conformity of EC Directive No.
89/336/EEC, when connecting power supply, it should be
considered guidance showing below.
* Do not share a common installation group with other
equipment.
* Be sure that supply network impedance is sufficiently low
≥

( Z RΩ). It may be necessary to consult the power
SYS
supply authority before connection of the air conditioner
to a low-voltage public network.
