This circuit diagram shows connections. (If the external static Pressure is less than 30 Pa, change to connections.)

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.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.
