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 (see
pg. 26).
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 LED for the smaller typeform ASD is provided in
LED is located on the front door of the enclosure of the larger ASDs.
