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
Figure 20 on pg. 24 ).
PA/+ and PB are used for the DBR connection. The DBR function is not used on the Q9 ASD.
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 Figure 2 . The Charge
LED is located on the front door of the enclosure of the larger ASDs.
