Notes
(1) If 2-value is indicated, the value in the [ ] is for water-cooled type.
(2) Depends on the specification, reverse phase relay is used.
(3) The air compressor using reverse phase relay, such as for 460 V/60 Hz, indicates a phase-lacking connection as reversal phase.
(4) Communication error details:
Port 1 (65) =Main circuit communication (Vtype), Port 2 (66)=Fan inverter communication (Air-cooled type)
Port 3 (67)= LCD communication, Port 4 (68)= Multiple unit control communication, Port 5 (63)= External communication
(5) If the thermistor is disconnected, override operation is not available. Contact the local HITACHI distributor/master dealer or representative office.
