Input Power Connectors

The following power connections are made to an Ultra1500 drive through a six
position terminal connector.
Main Power – L1, L2, and L3
L1 and L2 are single-phase main AC power input connections for the
2092-DA1, 2092-DA2, and 2092 -DA3 drives. L1, L2, and L3 are three-phase
main AC power input connections for the 2092-DA4 and 2092 -DA5.
Note: The L3 terminal is not used with the 2092-DA1, 2092-DA2, and
2092-DA3 models, as they require single-phase input power.

The main AC power inputs should not be removed and
re-applied at a rate exceeding once every 2 minutes. Ensure
that your control timing guarantees this minimum period to
avoid damaging the drive.
