Control Power – L1C and L2C
L1C and L2C are the single-phase control power inputs for all Ultra1500
drives. These AC inputs power drive logic and I/O circuitry.
DC Bus Negative – N
N is the negative side of the DC power bus on all 2092 drives.
Note: The positive side (P) of the DC power bus is provided on the DC Bus
and Shunt power connector.
If the 2092 drive is to be powered from a DC source, the DC power supply is
connected to P2 on the DC Bus and Shunt power connector, and N on the
Main Input power connector. The L1, L2, L3, and P1 terminals should be
disconnected.
The N terminal (labelled DC- on the removable connector) IS NOT an
