Power Connections
See Figure 19 on pg 26 for a system I/O connectivity schematic.
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.
Connect the input and output power lines of the ASD as shown in Figure 4 on pg 14 .
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.
The Charge Indicator LED provides an indication that there is a harmful voltage level present. The
location of the Charge Indicator LED is shown in Figure 3 .
Ensure that the Charge Indicator LED is off before coming into contact with any circuits or attempting
to perform any maintenance on the ASD.
