Timing Requirement s of the Drive Enable Input
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.
IMPORTANT
The drive requires 500 ms after the main AC input has
been applied before it can be enabled, as shown in Figure
2.25.
ATTENTION
!
The N terminal (labelled DC- on the removable connector) IS NOT an
Input Power connection.
