Motor ELB Power supply Do not remove the short-circuit bar between +1 and P/+2 when a DC reactor is not connected. U/T1, V/T2, W/T3 Inverter output terminal Connect to the motor. +1, P/+2 External DC reactor terminal Normally connected by the short-circuit bar. Remove the short-circuit bar between +1 and P/+2 when a DC reactor is connected. P/+2, N/- Regenerative braking unit connection terminal Connect optional regenerative braking units.
(If a braking torque is required) Ground terminal Ground (Connect to ground to prevent electric shock and reduce noise.) Motor ELB Power supply
