NOTE
1) Refer to the Wiring System Diagrams (Ref. next
page) for the meaning of “A”, “B”, “C”, “D”, “E”,
and “F” 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 Sys-
tem 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 (
