14 Q9 ASD Installation and Operation Manual
Connecting the ASD
Refer to the section titled Installation Precautions on pg. 4 and the section titled Lead Length
Specifications on pg. 18 before connecting the ASD and the motor to electrical power.
Power Connections
Contact With 3-Phase Input/Output Terminals May Cause
Electrical Shock Resulting In Injury Or Loss Of Life.
See Figure 20 on pg. 24 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 (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.
