Rockwell Automation 7000 PowerFlex Medium Voltage AC Drive (B Frame) - Classic Control - Manual (Page 202)

Commissioning 4-43
7000 “B” Frame 7000-UM150I-EN-P – June 2013
AC/DC Converter (PS1)
Every PowerFlex 7000 “B” Frame drive will be supplied with at
least one AC/DC converter. As the number of devices increases, so
will the number of AC/DC converters installed. The electrical
schematics provided by Rockwell Automation will identify how
many AC/DC Converters have been installed in the application being
commissioned.
Ensure the output of the supply is 56V DC. Refer to the Component
Definition and Maintenance section (Chapter 6) if adjustment is
necessary.

DC/DC Converter (PS2)
The DC/DC converter (refer to Figure 4. 15 ) has no provision for
output power adjustments. A green LED on the case of the power
supply indicates that the power supply is functioning properly.
Using a digital multimeter, measure each of the outputs of the DC/DC
converter to ensure that they meet the values specified on the
electrical schematics.
