16 H9 ASD Installation and Operation Manual
Connecting the H9 ASD
Refer to the section titled Installation Precautions on pg. 4 and the section titled Lead Length
Specifications on pg. 20 before attempting to connect the H9 ASD and the motor to electrical power.
Power Connections
Contact with the 3-phase input or output terminals may cause an electrical shock
resulting in injury or loss of life.
See Figure 20 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 (see
Figure 20 on 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 H9 ASD.
U/T1, V/T2, and W/T3 are the output terminals of the H9 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.
