Note:1.The dotted lines show field wiring.

2.The figure in the parentheses show field supply parts. 3.Color of earth wire is yellow and green twisting.

4.Not specified color of wire is brown.

5.Please remove the jumper wire (Mark) in the above diagram if you use the Switch <SW2> at local.

If the Switch <SW2> is not used, the Fan motor (indoor) drives at high speed.

6.Specification subject to change without notice.

Caution,

1.To protect each Fan motor and Compressor from abnormal current, Over current relays <51C>, <51F1,2> are installed. Therefore, do not change factory set value of Over current relays.
