See the Typical Connection Diagram on pg. 26 for a system I/O connectivity schematic.
An inductor (DCL) may be connected across the PO and PA/+ terminals to provide additional filtering.
When not used, a jumper must be connected across these terminals.
PA/+ and PB are used for the DBR connection if using a braking resistor.
PC/- is the negative terminal of the DC bus.
R/L1 , S/L2 , and T/L3 are the 3-phase input supply terminals for the ASD.
U/T1 , V / T2 , and W/T3 are the output terminals of the ASD that connect to the motor.
The location of the Charge Indicator LED for the smaller typeform ASD is provided in Figure 2 . The
Charge LED is located on the front door of the enclosure of the larger ASDs.
