NOTES:
(1) Depends on the specification, reverse phase relay is used.
(2) The air compressor using reverse phase relay, such as for 460 V/60 Hz, indicates a phase-lacking connection as reversal phase.
(3) Communication error details:
Port 1(65) =Main circuit communication (Vtype), Port 2 (66)=Fan inverter communication (Air-cooled model)
Port 3 (67)= LCD communication, Port 4 (68)= Multiple unit control communication, Port 5 (63)= External communication
