Do not connect the compressor to power supply until all wiring and connections are 

completed.

 

 

 

 

 

Disconnect the input power connector at REMOTE/RESPONSE wiring. Failure to observe 

this precaution could result in damage to, or destruction of, the equipment. 

 

REMOTE WIRING 

 

:Set the REMOTE/LOCAL switch to 

REMOTE

 position. 

Make the REMOTE wiring according to the circuit diagram shown in 

Appendix B. Always use the momentary switch (contact) for setting 

START/STOP push button switch (PB1, PB2) in remote operation. 

RESPONSE WIRING

 

:Be sure to make wiring for RESPONSE signals. The relay 

specification of response signals is shown in Appendix B.
