12 P9 ASD Quick Start Guide
Connecting the ASD
Refer to the section titled Installation Precautions on pg. 4 and the section titled Lead Length
Specifications on pg. 16 before attempting to connect the ASD and/or the motor to electrical power.
Power Connections
Contact With 3-Phase Input/Output Terminals May Cause An
Electrical Shock Resulting In Injury Or Loss Of Life.
See the Typical Connection Diagram on pg. 22 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 Indicator LED is located on the front door of the enclosure of the larger ASDs.
Note: The Charge Indicator LED shown is of the 1 HP P9 ASD. See the accompanying
drawings of your received P9 ASD for the actual location of the Charge Indicator
LED.
