Single-phase power supply (ATV71H 075M3 to U75M3)
Diagram with line contactor
Diagram with switch disconnect
(1) Line choke, if used (compulsory for ATV71H U40M3 to U75M3 drives)
(2) Fault relay contacts for remote signaling of drive status
Inhibit the input phase loss fault (IPL) so that ATV71H 075M3 to U75M3 drives can operate on a single-phase supply
(see Programming Manual). If this fault is set to its factory configuration, the drive will stay locked in fault mode.
Note: Install interference suppressors on all inductive circuits near the drive or connected to the same circuit (relays, contactors, solenoid
valves, etc).
